How Long Do Hens Sit On Eggs
Hens sit on eggs for about 21 days. During this time period, hens do not lay eggs anymore and may also become aggressive and defensive toward their eggs. Hens are known to brood over the eggs of other hens or even egg-like objects like stones.
If you love the idea of incubating eggs naturally, and have a chicken that is of a suitable breed, you are going to want to get a chicken that goes broody and sits on eggs. You can encourage your hen to go broody by leaving artificial eggs in her nest over a long period.
As previously established, if the hen leaves the nest for three to four hours, the eggs should still be warm enough for them to hatch. If temperatures are freezing or extremely cold, three or four hours may be too much time for her eggs. While a final answer has to take into account outside temperatures, how far along an egg is, and how many eggs are in the nest, letting broody chickens keep their eggs around four hours is generally safe.
Some eggs can take a bit longer to hatch, up to 26 days, and thus a hen might need to stay with her eggs longer. The average time for eggs to hatch is 21 days, and the broody hen will sit on her eggs throughout that whole time, often being aggressive with whatever or whoever comes close. The hen will not sit on her eggs until a complete clutch has been laid; this will ensure all chicks hatch around the same time.
The mother hen will spend the majority of the 21-day period sitting on the eggs, leaving very briefly to feed and water. A hen might leave her eggs 10-15 minutes at a time for a meal, but will feel anxious to go any longer; reducing the distance she has to walk for a meal will allow her to spend more time sitting on the eggs, and as a result, become more broody. A hen will require layered food about one month after she hatches, since she can start to lay eggs any time after five weeks.

A hormonal change causes a hen to establish a nest, and then lay one egg daily–she may even steal eggs from nearby nests until she feels like she has enough to nest. If a hen has a dark, comfortable, uninvaded place she can nest, she can roll her clutch of eggs (usually 12-14) into a darker area and start to brood.

The hen may also keep rolling in more eggs, trying to keep up with the number of eggs sitting there, over a dozen is not unusual. She will pull feathers off of her own breasts, to ensure her damp, warm skin keeps eggs warm, she will also use feathers to provide insulation to a darker area. Sometimes eggs found outside of the nest are viable, and sometimes a hen continues sitting on bad eggs to the bitter end. She will then proceed to sit on the 12 eggs 24 hours per day, for 21 days in a row, for them to hatch.
A broody chicken will stay on its eggs until they are ready for hatching — in most cases, that works out at around 21 days. The hen will sit on eggs for around 21 days, providing the necessary heat to allow the embryos to develop into the chick, and ultimately to hatch out into the world. Left unattended, the hen will remain broody for about 21 days, the amount of time needed for the clutch to hatch a clutch of fertile eggs. Left to its own devices, the broody will lay a clutch of eggs, then stop egg-laying and stay with them for 21 days (more or less) until they hatch.
Slip a few fertilized eggs underneath the broody, and with some luck, within 21 days, she will have produced a few chicks for you. She will also keep her chicks warm and safe in their early days, until they are able to become curious and begin exploring their world. If a broody chicken actually does try to attack or kill its own chicks, its chicks should be removed for safety and put into the brooder, unless you have another chicken willing to take them. Remember, if you then remove her broody chicks from the existing flock, then at some point, she must introduce herself again (another stressor for her).
Personally, I keep them right where they are just in case a broody deserts her nest — apparently most broody birds prefer to stay in one place, so moving her might encourage her to leave the eggs. I have found in my experience that the best time to check these eggs is once A broody has left the nest to eat. If your chicken is laying eggs, it will be sitting on the nest for two weeks, but it could very well have been broody for as long as six weeks. If the hen, who is too young to become a mother, attempts to get past this three-week incubation period, sometimes breaks eggs or kills the chicks as they hatch.

Since most people today rear chickens strictly for eggs, and are not worried about their flocks propagating themselves, a hen that stops producing eggs as soon as it goes broody is counterproductive for todays backyard chicken raising. This is all well and good if your chickens actually have eggs that are ready for hatching, but occasionally, the hen will be sitting on eggs that are not fertilized, or even imaginary eggs. Adding non-fertilized store-bought eggs, or even faux rubber eggs, can prompt your hen to sit on them, thereby increasing the chances she can successfully incubate any viable fertilized eggs that she has laid. If your broody hen is sitting on a clutch of fertile eggs in her nesting box, and you are okay with adding some young chicks to the flock, then it is perfectly fine to let her sit on these eggs.
