Short answer: Most disease losses on a Ghana farm come from a missed date, not a missing product. Build one calendar that runs by bird age, from arrival to culling, and lay it over the seasons: the rains bring wet litter and coccidiosis, while the harmattan brings dust and cold nights that stress the lungs. Vaccination timings in the calendar are typical examples only. Follow your vet's advice for the actual dates, and record what was done when.
Key takeaways
- Write the calendar from the day the birds arrive, by age, then mark the seasons over the top.
- Vaccination dates come from your vet's programme. The timings in this article are typical examples, not instructions.
- The rains and the harmattan change the risk more than most farmers expect, so the calendar should change with them.
- Put cleaning, water checks, rodent checks and footbath days on the same calendar as the vaccines.
- A missed date is a question for your vet, not a reason to double the next dose.
The vaccine was in the fridge, and the bird was already past its day
We hear some version of this every rainy season. The birds are coughing, a few have died, and the vaccine that should have gone in weeks earlier is still sitting in the fridge, unopened. Nothing about the product was wrong. The date was.
In our experience, most prevention failures on Ghana farms are timing failures. The vaccines are available. The feed is bought. The problem is that a dozen small jobs fall on different days, and nobody has them on one page. One clear calendar fixes more than a new product does.
This article gives you a calendar you can copy. The ages and months are typical examples. Your vet's programme for your birds, in your area, is the one to follow, and where the two differ, the vet wins.
Build the calendar on one page, starting from arrival day
Use one sheet of paper or one page of the record book. Do not spread the plan over three notebooks and a phone. Build it in this order.
- Write the arrival date at the top, with the number of birds, the breed and the house.
- Count forward in weeks, so you have a line for every week of the flock's life. Layers need the line for the point of lay and beyond.
- Mark the vaccine days from your vet's programme, and the batch record from the hatchery if the chicks came from us.
- Mark the routine jobs: water tank cleaning, drinker checks, litter turning, rodent and predator checks, footbath refills and the weekly weigh-in.
- Lay the seasons over the top in a different colour, or with a note in the margin. Rain and harmattan months should be obvious at a glance.
- Add the clean-out date, the rest period and the day you restock, once the flock is sold.
Pin the calendar where you will see it every day, such as the feed store door or the inside of the house door. A calendar in a drawer does not prevent anything.
The first three days decide how much work the next six weeks are
Chicks that arrive in good order, with a batch record and a clean brooder, are already in a stronger place than most. Before a chick leaves us, our hatchery programme has handled coccidiosis, infectious bronchitis, Gumboro, Newcastle and Marek's, and the batch record notes the date of each step. Keep that record with the calendar, because it tells your vet where to start.
Days one to three are for warmth, water and a clean start, not for extra products. Give clean water first, then feed. Watch the chicks at the edge of the brooder for huddling, which means they are cold, and for birds that stand apart, which means something is wrong. Our article on the first 48 hours of chick care covers the routine in detail.
Do not give any vaccine or medicine on arrival unless your vet has told you to. Some farmers add products to the water out of habit. That habit can mix badly with the hatchery vaccines and it adds a dose nobody recorded.
The first six weeks, when mistakes cost the most
The first six weeks are where a flock is made or broken. Young birds have less protection, they are in the house all day, and any dirty drinker or wet corner gets used by all of them. The calendar here is a typical example for a meat flock. Layers use the same thinking with a different timetable.
| Age | Typical prevention focus | Typical example, to check with your vet | Your daily or weekly check |
|---|---|---|---|
| Days 1 to 3 | Warmth, water first, quiet house | No extra products unless advised | Crops filling, chicks spread evenly |
| Week 1 | Clean drinkers and dry litter | Hatchery vaccines already given | Litter dry at the edges, no wet patches |
| Week 2 | Gumboro and Newcastle protection | Booster drops or water doses around this time | Eyes, breathing, droppings, water intake |
| Week 3 | Gumboro window and gut health | Gumboro vaccine timing set by your vet | Feed intake, weight sample of 10 birds |
| Week 4 | Respiratory watch | Booster for respiratory diseases if your vet's plan includes it | Cough at dusk, nasal discharge |
| Weeks 5 to 6 | Coccidiosis and worms | Control plan set with your vet | Droppings, litter wetness, weight |
Treat the table as a list of questions for your vet, not a list of orders. Ask which vaccines your birds need, by which route, and at which age. For Gumboro in particular, the timing matters, and our article on the Gumboro guide explains why a bird that is too young or too old at the wrong moment can be poorly protected.
Pullets and the run-up to lay
Pullets are the group most farmers forget. They look fine, they are no longer chicks, and so the calendar goes quiet for a few weeks. Then they start to lay, and a respiratory problem or a drop in the flock shows up at the worst time.
- Weeks 7 to 10. A typical example is a pox vaccine for pullets in areas where fowl pox is common, and a check that the flock is on the planned weight line. Our notes on fowl pox in chickens explain the wet-season risk.
- Weeks 10 to 14. Worm control and a mite and lice check, timed with the vet's advice. Our article on worms and deworming covers the signs, and mites and lice covers the external pests.
- Weeks 14 to 18. The pre-lay boosters for respiratory and other diseases, as set by your vet. Move the birds into the laying house only after the house has been checked and cleaned.
- Point of lay. Watch the flock daily for the first eggs, and keep a note of the date the first egg appears in the record.
Pullets from a bought-in source should go through quarantine before they join your flock, as set out in our article on quarantining new birds. A bird that arrives at point of lay without a plan is the hardest kind of bird to protect.
Laying hens through the year
Once a flock is laying, the calendar changes shape. The aim is steady eggs, a steady flock and no surprises. Layers are kept longer than broilers, so the calendar runs for many months, and the seasons matter more.
- Every month. Clean the water tank and the drinkers, check the feeder and the litter, look for rodents, and refill the footbath at the door.
- Every three months. A review of the vaccine record with your vet, and a check of the flock's weight and egg output against last quarter.
- Once or twice a year. A deeper clean of the house, with the birds out, and a fresh look at the ventilation and the nest boxes. Our article on cleaning a poultry house between batches gives the full routine.
- When egg output falls. Call your vet early. A sudden drop is a signal, not a nuisance, and waiting for it to pass often means losing weeks of eggs.
Keep antibiotics out of the routine calendar. They belong to the sick-bird column, with a vet's name against them and a withdrawal date written down. Our article on responsible antibiotic use sets out the rules we would apply to any flock.
Laying the seasons over the top of the calendar
In most of southern Ghana the main rains run from about April to July, with a shorter rain around September and October. The harmattan usually comes from December to February, bringing dry dust, cold nights and low humidity. The north has a longer dry season. Your local pattern may differ, so mark the weather you actually see, not the one on the wall.
| Season | What changes on the farm | Prevention focus | Calendar actions |
|---|---|---|---|
| Main rains | Wet litter, damp corners, mosquitoes, muddy runs | Coccidiosis, respiratory and pox risk | Litter checks twice a week, pox and coccidiosis plan confirmed with your vet |
| Short rains | Rain in bursts, humidity, warm afternoons | Gut problems, wet droppings, heat | Ventilation check, drinker check, footbath kept full |
| Harmattan | Dust, cold nights, dry air | Respiratory problems, mould in feed and litter | Cover open sides, check feed for mould, watch birds at dusk |
| Hot dry spells | High afternoon heat, poor water intake | Heat stress and dehydration | Extra water checks, cooler house, feed moved to cooler hours |
Each season asks for something different from the same calendar. In the rains, litter is the first thing to check. In the harmattan, it is the feed and the lungs. The rainy-season pieces, such as our article on rainy-season management, and the harmattan care guide go deeper on each.

The master calendar, by age and season together
When you are putting the calendar on the wall, it helps to see the two sets of marks together. This is the version we would tape to the feed store door. The vaccine timings are typical examples. The seasonal actions are the same whatever the flock is.
| When | Bird stage | Typical prevention job | Season note |
|---|---|---|---|
| Arrival week | Chicks | Warm brooder, clean water, batch record filed | Dry season: check the brooder for draughts |
| Weeks 2 to 3 | Chicks | Typical Newcastle and Gumboro timings, as your vet sets them | Rains: keep the litter dry around the drinkers |
| Weeks 4 to 6 | Growers | Coccidiosis and worm control plan, weight checks | Rains: coccidiosis risk is highest here |
| Weeks 7 to 10 | Pullets | Pox vaccine where advised, pest checks | Rains: mosquitoes and pox risk |
| Weeks 14 to 18 | Pre-lay pullets | Pre-lay boosters, house clean before moving in | Harmattan: check house cover and feed |
| Point of lay | Layers | Daily egg count, monthly tank and drinker clean | Hot spells: water and shade checks |
| Every quarter | Whole flock | Vet review of records, weight and output check | Plan the next season before it arrives |
| Between flocks | Empty house | Full clean, disinfect, rest the house | Choose a dry spell if you can |
The jobs nobody puts on the calendar, and why they matter
Vaccines get the attention, but the small jobs do most of the preventing. Put these on the calendar as firmly as the vaccine dates.
- Footbath refills. A footbath that has run dry for a week does nothing. Refill it at the same time every visit, and keep a note.
- Water tank cleaning. Empty, scrub and refill on a fixed day each month. A dirty tank is a steady source of gut and respiratory trouble.
- Rodent and predator checks. Rats carry disease and eat feed. Check the traps and the holes weekly. Our piece on rodent and snake control covers the details.
- Visitor days. Note who came onto the farm and when. Visitors who go near the flock are the people you most need to record.
- Feed checks. Look at the feed bags every week for damp, clumping, or a musty smell. Mould in feed is a calendar item, not an accident.
Our article on biosecurity on a poultry farm shows how these small jobs fit together into one routine.
When a date gets missed, what to do next
Every farm misses a date sooner or later. A vaccine is late because the vet was away, the rain stopped the trip, or the birds were moved in a hurry. The panic move is to double the next dose, or give the vaccine early to catch up. Do not do either without advice.
- Write down the date that was missed, and the reason, in the calendar.
- Call your vet and tell them the exact birds, the age and the product you have. Ask what to do next.
- Follow the vet's instruction for the catch-up, and write the new date on the calendar.
- If birds show signs of disease while you wait, do not wait for the next calendar date. Call the same day.
A missed date is information. If you miss the same date every year, the calendar is in the wrong place or the job is too hard for one person, and that is a sign to change the plan, not to blame yourself.
Questions farmers ask
Do I need to follow the vaccine timings in this article?
No. The timings here are typical examples to help you ask good questions. Your vet knows your birds, your area and the diseases around you, and their programme comes first. Use this article to build the calendar, and let your vet fill in the actual dates and products.
Are the chicks from you already vaccinated?
Yes, chicks from us leave the hatchery already protected against several of the main diseases. Each batch comes with a record of what was given and when. Keep the record with your calendar, and ask your vet what, if anything, is still due on your farm.
What is the single most useful thing to add to a prevention calendar?
The water tank and drinker clean. It is cheap, it happens monthly, and it prevents a lot of gut and respiratory trouble. Put it on the calendar with a fixed day, and record the date each time. In our experience, the farms with recurring flock problems are often the ones with no regular tank clean on the books.
How does the rainy season change my calendar?
Wet litter raises the risk of coccidiosis and respiratory problems, and mosquitoes raise the risk of pox. Check the litter more often, keep drinkers out of the wet, and talk to your vet about the pox and coccidiosis plan before the rains start, not after the first deaths.
What should change in the harmattan?
Dust and cold nights stress the lungs, and dry feed can grow mould if it gets damp at night. Cover the open sides of the house, check the feed for mould, and watch the birds at dusk for breathing problems. Do not seal the house so tightly that the air goes stale.
Can I give antibiotics on the calendar as a precaution?
No. Antibiotics are for birds that a vet has diagnosed, and they carry a withdrawal period that affects the eggs and meat you sell. Keep them off the routine calendar, and use them only on your vet's advice, with the date and product written down.
How often should I call the vet for a routine check?
Ask your vet to set a regular review, at least every three months for a laying flock, and before you restock. A review lets you check the records, the vaccine plan and the flock's weight and output, and it gives you someone to call when something looks wrong.
