Yes.
It depends on whether there is a rooster around to fertilize the eggs. Broiler hens lay eggs that can grow into chicks just as typical egg-layers do - otherwise we wouldn't have broiler chicks to raise.
no
A hen
They sit in the hen house on eggs, on the roost or in a nest.
If the hen turkey is nesting let her incubate the eggs. If you have a good broody chicken hen let the hen incubate the eggs.
Yes, not all eggs hatch even when a brood hen tends them. "Fake" eggs are available for use when a breeder needs a hen to hatch only a very few eggs. The hen will care for any egg in the nest when she broods.
Yes, only the hen sits on eggs.
No, fertile hen eggs need to be incubated at the proper temperature and humidity levels to hatch successfully. Simply sitting in hay will not provide the ideal conditions for the eggs to develop and hatch.
They don't. They lay eggs that hatch.
No. The guinea hen does not have to sit on the eggs. You should put them in an incubator.
A brooding hen is a female chicken that exhibits maternal behavior by sitting on a clutch of eggs to incubate them and keep them warm until they hatch. During this time, the brooding hen can be protective, aggressive, and focused solely on caring for her eggs.
It depends on the size of the hen.. But most probably 10 or 11.
