I have a broody silkie who is sitting on two fertilized eggs. This is my first time hatching eggs with a broody hen. After a few times of her getting off the nest to eat and then returning to the wrong nest box and incubating infertile eggs, I put up hardware cloth in my chicken coop to close her inside. She has access to food and water and half the coop with her nest box, my other 4 hens have the other half of the coop and three nest boxes. Her eggs are looking great and should hatch tomorrow or the next day. How long should I keep her and her chicks separated from the rest of the flock? I'd like to socialize them as soon as possible, but don't want anyone to get hurt. I have no roosters, just a total of 5 pullets. Will my silkie defend her chicks if the other chickens get aggressive?
