A broody hen will sit on her clutch all day every day, only occasionally leaving them for short periods in order to take food and drink. She will keep the eggs warm and moist and turn them over now and again. While turning, she will move the eggs on the outside into the center.
Eggs on the outside will be slightly cooler than the eggs in the middle. If the eggs get too cool the fetus will perish. If a hen has more than about a half dozen eggs or so, the eggs will spend too much time on the outer edge of the clutch and will die. When the hen moves the eggs around, the eggs from the middle will be moved to the outside, leaving the hen sitting on a clutch of dead eggs. This is why hens stop laying-to give a few eggs the best chance of survival.
THE LAZY HEN
When a hen goes broody, other hens may give her the boot from her nest in order to lay their own eggs into the clutch to let the broody hen do the work of incubating the eggs. When done, this lazy hen moves on, allowing the broody hen to go back to doing her thing. I once had a broody hen sitting on about 2 dozen eggs, mostly laid by other hens. She sat and waited for days. Being inexperienced in this area of chicken behavior, I let her sit for about a month. Even a big fat hen can not cover and keep 2 dozen eggs warm. As the eggs were moved to the outside, they died. After a month, the eggs began to break, leaving a smelly mess and a stubborn hen. If you have a hen sitting on a clutch, you would do well to segregate that hen from the rest of the flock. Let her do her thing in peace. The reward is likely to be a few more birds.
