My big brahma rooster Earl seems to be paying a lot of attention to one of our Australorps. He's following her around everywhere she goes. I went into the coop to look for eggs and they were both behind the door clucking. She was trying to make a nest, I think, and he was looking over her back kinda supervising. When I came in, they went outside and whereever she went Earl was right behind her. He wasn't trying to breed her. Why would he be doing this? And why won't the hen lay in the nest boxes? I've got "eggs" in the boxes but she doesn't want to go in there. What else can I try?
