Good luck to him on that! Momma hens are mean and can easily make the meanest roosters high tail and run!Haha yes chicken math.... So I've heard. Of course she will keep them until they can be seperared. I cld never pull them apart. I have a full sized barn that they all use. I just have to find a way to separat them. My rooster is a meanie and will go after them as soon as he knows they are there.
