how long does a hen sit on eggs
Time the Hens Set It only takes 21 days for fertile eggs, properly incubated by a hen or in an incubator, to hatch. Note that this number begins not when the first egg in the clutch is laid, but when the hen stops laying and begins the setting process.he average chicken lays about one egg every other day, and she, depending on her size, will likely make a clutch of 4-10 eggs. Once she stays on the nest fully for one whole day, you can count that as the first day of incubation, and start the 21 day countdown :).
