I have a flock of hens who have grown "stuck up" to the roo that is in with them. He is an older gentleman and getting pretty long in the tooth. They are starting to avoid his more romantic advances. I have a beautiful EE rooster to take his place. He has the company of two young hens. At the time of purchase at the local TSC I was informed all would be pullets. I was shocked to find one of them a rooster. I am glad I didn't cull him because of the way the ladies are acting around my elder roo Spurs. I was wonder if this happens very often? Why would the hens reject the roo when he gets a little older? And how do I introduce them to the new roo and his present ladies? Any advice would be appreciated.
