27 through 89 days
Once a hen has been mated by the rooster her eggs will remain viable for up to 10 days or longer.
yea they do
No.
a hen can still lay fertilized eggs up to 30 days after contact with a rooster
Hens lay eggs without a rooster. It is only when the rooster fertilises the female's eggs that he will affect the egg production. (After fertilisation the hen will lay a clutch of fertile eggs which she will hatch.)
If you are taking about the hen sitting on eggs then it will make things easy for you and the hen. you will have a better outcome if you move the hen or take the rooster out.
No, a hen cannot lay a fertilized egg without exposure to a rooster. However, a hen can lay fertilized eggs up to a week after the male is taken out of the flock.
Yes.
They sit on them as soon as the egg is laid. They will continue sitting on the eggs until they hatch. This keeps the eggs warm. If you gather the eggs every day, the hens are less apt to sit on them. Sometimes their maternal instincts kick in and they will sit on the eggs. When that happens you can just reach underneath and pull the eggs out. They may peck at your hand, but it doesn't hurt.
Absolutely yes. A hen does not need a rooster to produce eggs, she only produces fertile eggs when a rooster is involved. Many farm flocks do not have a rooster among the flock and egg production does not suffer in the slightest. A rooster job is to protect the flock and mate with the hens to produce offspring but the hens will continue to lay eggs with or without him.
The hen will lay eggs whether there is a rooster on site or not. In fact, commercial layers (the eggs in the grocery store) never, ever see a rooster. They live in a hen commune. You only add the rooster if you want to have chicks. If you keep the rooster just because he's pretty, he eats the food, bothers the hens and doesn't give you anything in return except something nice to look at.
No. The rooster has relations with the hen and she lays fertilized eggs
