He is a bad rooster at times. He will be 1 yr old next month. He is sweet with me and sweet to his girls most of the time. His girls are 5 months and 4 months. BUT he is not always nice to one. The other day he decided to try and mate with the 4 month old. She wanted no part of it. So he grabbed her by the neck and started slamming her on the ground. I yelled SodaPop stop it. I ran into the run and beat his hiney. (NO I did not hurt him) He kept running away and I kept chasing him fussing at him. After that I left him alone and he was being sweet again. Than yesterday I hear my 5 week old guinea hollering and there he is trying to mate with it. So I yelled at him again. UUUGGGHHHHH what is his problem? Is this normal behaviour? I have another rooster with 4 month old hens and he does not do that to them.
