I have a giant Cornish Cross hen who is an excellent layer and a tiny Ameraucana Bantam rooster. Lately I have been seeing her with blood on her. Today I witnessed the tiny rooster attacking her. She was running from him. When he caught her and she surrendered and put her head down, he began PICKING her!, pulling out her feathers and picking her on her head back and bottom drawing BLOOD! It looked for a moment like he was trying to mount her but it seemed he couldn't so it appeared that he decided to kill her instead!! I grabbed her and put her in a pen by herself. She has tiny peck wounds on her that seem insignificant, but if I had not intervened, I fear he may have nearly killed her. What does this behavior seem to be? Do i have a psycho dwarf Ameraucana? Or does he have an unfulfillable crush on the big girl? I have about eight roosters that are all probably coming into puberty. Will I have to isolate them from the hens? Are they all going to go psycho like him in a few weeks? What is going on please? PS I have watched my Pekin ducks mating and it was nothing like this. They just mounted and got off. This fellow seemed to be like a fighting rooster trying to kill another! I will not have this on my ranch. Do i need to dispatch him and put him in a stew or just keep them separated?
