I have 11 hens and two roosters (One EE and one Silkie) I just found my first two eggs today and now it seems like the roosters are trying to keep the hens in the house. (they normally free-range) Is this normal and should I try to keep the roosters out so the hens can lay in peace? Also is it OK to have two roosters with that amount of hens or should I find a home for one of them?
