Short answer: A broody hen stops laying for as long as she sits, so every sitting bird costs you eggs each day. In a flock, broodiness shows up as a small but steady loss that adds up over a season. Count the broody birds every morning, act early, and decide in advance whether you want to hatch or break the habit. Eggs from layers only hatch if a rooster has mated the hens, so check fertility first.
Key takeaways
- Count the broody hens every morning and write the number down, so a rising trend shows up early.
- A broody hen stops laying while she sits, and the eggs lost across a flock add up quickly.
- Broodiness is driven by hormones and encouraged by quiet, dark nests, so change the nests before you blame the bird.
- Eggs only hatch if they are fertile, so confirm a rooster is with the flock before you plan a hatch.
- Decide early whether to break or use a broody hen, because a week of waiting makes either choice harder.
- Heritage and dual-purpose breeds tend to sit more often than commercial brown layers, so breed choice matters.
Counting broody birds at dawn, every day
Most flocks have a few broody hens at any time, and the owner notices only when a hen growls at a hand in the nest. A better habit is to walk the house at first light, before the hens leave the nests, and count the birds that are sitting, puffed up and reluctant to move. Write the number in the flock book beside the date and the house temperature.
One count tells you little. Three or four weeks of counts tell you a story. If the number climbs from one or two to six or eight in a week, something in the house has changed, and the cause is usually in the nests, the light or the feed. Keep the count simple, have the same person do it at the same time each day, and the trend will be easy to read.
Why a layer goes broody: hormones, nests and light
Broodiness is driven by hormones, mainly prolactin, which rises when a hen spends long hours in one place and is stimulated by warmth and darkness. A hen that finds a dark, quiet box and stays in it is more likely to set. A hen that is crowded, bullied or disturbed may also keep returning to a quiet nest. Light plays a part too. Long days with bright light are often linked with less sitting, while short, dim days favour it.
Breed matters a great deal. Heritage birds and many dual-purpose breeds sit far more often than commercial brown layers, which have been selected largely for egg output. Some commercial layers still go broody now and then, and an older hen that has laid heavily may start to sit as her lay fades. If a flock goes broody often, check the breed against the job you want it to do, using the breed guide, and check the nests before you accept that the birds are simply broody by nature.
What a broody hen costs in eggs, with a worked example
A hen in full lay may produce about five or six eggs a week in good conditions. A broody hen stops laying while she sits, and then takes some days or weeks to return to lay once she is broken. Count from the day she is first seen sitting to the day she starts laying again, and multiply by her normal weekly output. Even one bird can cost a month of eggs.
| Scenario (hypothetical flock) | Broody hens | Weeks off lay each | Eggs lost (approx.) |
|---|---|---|---|
| 100 layers, 2 broody for 3 weeks | 2 | 3 | About 30 |
| 100 layers, 6 broody for 3 weeks | 6 | 3 | About 90 |
| 400 layers, 10 broody for 4 weeks | 10 | 4 | About 200 |
These figures are hypothetical and use five eggs a week per hen. Your own rate will differ with breed, age and feed. Put a value on the lost eggs at your own selling price, and compare it with the cost of a breaking routine or a better nest. Use the layer egg profit calculator to turn the lost eggs into a monthly figure for your own flock.
Letting a broody hatch: fertile eggs first
A broody hen hatches only fertile eggs, which means a rooster has mated the flock and the eggs were laid after that. Many commercial layer houses have no rooster, or too few for the number of hens, so the eggs under a sitting hen will never hatch. If you are not sure, hold a few eggs up to a torch in a dark room after about a week, and look for the veins and the dark spot of a developing embryo. Eggs that show nothing are not fertile.
If you do want a hatch, choose a calm hen of a known breed, sitting on eggs of known age and fertility, in a quiet corner away from the rest of the flock. Check her for mites and lice, and treat her with a product your vet or agrovet recommends. For dates and timing, the egg incubation calculator helps you plan the hatch day, and our blog covers the wider routine of hatching with a hen.
Breaking a broody hen without stressing her
If you want her back on the lay, the aim is to make the nest unattractive and to move her off it firmly and often. Lift her off the nest in the late afternoon, put her in a cool, sheltered spot with feed and water, and check that the nest she came from is not inviting. Repeat for as long as she keeps going back. Do not leave her hungry to make a point, because a hungry hen will simply return to the nest to rest.
Do not confuse a broody hen with a sick one. A hen that is off her feed, pale around the comb, or losing weight may be unwell, and sitting is only part of the picture. Check her closely. If she does not respond to a day or two of handling, speak to a vet or a veterinary officer before you spend more time on it.
How a nest keeps a hen sitting, and how to change it
A hen sits where the nest is quiet, dark and warm. If one box sits in a corner with little traffic, its owner will sit there, and her presence can encourage others to join her in the same box. Look at the nest layout through the eyes of a hen. Is the box closed on the sides? Is it cool in the afternoon? Is it at a height where the flock walks past it all day?
Remove eggs at every collection, fill any gaps with fresh litter, and open the front of the nest so light reaches it. Good light, regular egg removal and a nest that other hens use all day turn a comfortable sitting spot into a boring one. Do this for the whole house at once, not one box at a time, so the flock does not simply move its sitting to another corner.
Feed and water for a sitting hen in the heat
A broody hen eats and drinks less while she sits, and she leaves the nest only briefly. In the Ghanaian heat, a hen that spends hours in a warm box can dehydrate quickly. Put feed and water within a short walk of her nest, and clean the drinker every day, because sitting hens tend to foul their water with droppings.
When you break a hen, give her normal layer feed and fresh water, and let her come off the nest to eat at least twice a day. A well-fed hen is calmer, and a calm hen is easier to move. Keep the layer ration on track for the whole flock as well. The poultry feed calculator helps you work out how much feed the flock needs each week, so a few sitting hens do not throw the numbers out.

Rainy season, mites and a hen that sits for days
In the rains, a damp nest encourages mites and lice, and a broody hen who sits for days gives them a perfect place to build up. Check her vent and the skin under her wings at night with a torch. Change the litter in her nest, treat the bird and the nest with a product your vet or agrovet recommends, and read the label before you use it. Do not spray products near her face or eyes.
Mites are often missed because they hide during the day. Check the nests in the evening, when they come out to feed. A flock that has mites will lose lay and condition whether or not any bird is broody, so the same check protects the whole house.
When to keep a broody hen, and when to move her on
A hen that goes broody once in a season is usually a normal bird with a normal habit. A hen that sits every few weeks, year after year, costs eggs and feed without paying either back. For a commercial flock the decision is economic. Set a limit, such as a hen that sits three times in one laying cycle, and move her out of the layer house when she reaches it.
If you replace a hen, the price depends on the strain. Hy-Line Brown day-old chicks start at GH₵ 23, and Lohmann Brown is quoted on request, so check the chick price list before you decide. If a hen is past her best, the layer chicks for sale page shows the options for a new batch.
For a backyard flock, a broody hen is often a joy, and a good mother may be worth keeping for her chicks. Decide by what the flock needs, and write the decision in the record book so you are not reopening the question each time she goes broody again.
The broody log: what to write down each week
A short weekly log turns a bad week into a pattern you can act on. Keep the same columns in the same order, so a glance at the book tells you what changed.
- The date, and the number of broody hens counted at first light.
- The house temperature at the time of the count, and any unusual hot or cold nights.
- Any change to the nests, litter, light or feed in the past seven days.
- Any mites, lice or sick birds found at the evening check.
- The action taken, such as moving birds, changing litter or calling the vet.
- The total eggs collected, so you can compare lay with the broody count.
The same book is a good place to record vaccination dates. The poultry vaccination schedule calculator helps you plan the dates, so that a broody spell does not hide a missed dose.
A season plan for broodiness across the year
Broodiness tends to rise when nests are quiet and the weather is warm, so the hot months in Ghana need the most watching. Before the heat arrives, check the nests, the light and the collection routine, and set a count that you will act on. Use the first rains to review the mites and the litter, because damp weather changes the nest quickly.
The harmattan brings its own changes: dry, dusty air, cooler nights and more time indoors, which keeps hens in the nests for longer. Plan your nest checks for those weeks, and keep the house ventilated without draughts. If you are looking at the wider picture of a poultry business in Ghana, the poultry farming in Ghana guide sets out the seasonal calendar for the whole farm.
Questions farmers ask
How do I know if a hen is broody or just laying?
A broody hen sits on the nest all day, puffs her feathers, growls or pecks when you reach under her, and will not leave to feed. A laying hen visits the nest briefly, leaves to eat and drink, and does not stay put. If you are unsure, look for a hen that is still on the nest at mid-morning, with no egg laid that day.
Will a broody hen lay again after she has been broken?
Usually yes, but it takes time. Once she has stopped sitting and eats and drinks normally, most hens return to lay within a few weeks. A hen that keeps returning to the nest may need a change of place or a decision to move her on.
Can I use a broody hen to hatch eggs from my layers?
Only if the eggs are fertile, which means a rooster has mated the flock. Many commercial layer houses have no rooster, so their eggs will not hatch. Check a few eggs with a torch after about a week before you assume a hatch is coming.
Is it cruel to break a broody hen?
Breaking a hen is a normal part of flock management when done gently. Move her off the nest, give her feed and water, and do not leave her in a bare pen for days. If she is stressed, unwell or does not respond to handling, a vet should look at her.
Do broody hens get sick more often?
They are not more likely to be sick because they sit, but they can pick up mites and lice more easily because they stay in one nest. Sitting also means less feed and water, which can weaken a bird in the heat. Check her closely, and seek veterinary advice if she is pale, weak or losing weight.
Should I cull a broody hen?
Not automatically. A hen that sits once in a season is often worth keeping. A hen that sits repeatedly, and costs more in eggs and feed than she lays, is a reasonable candidate for replacement. Decide by your own limit and record the decision.
