Below is my 5 month old Turken cockerel/rooster. He is a huge boy (7 pounds already) and just started crowing and courting the ladies. He tends to go after the more submissive or younger pullets since they are easy targets and are not as likely to fight back. The problem is that he seems to be very rough with the hens. I have had other roosters that have always been gentlemen with the ladies. He, on the other hand, will grab them by the neck and not let them go until he has ripped out a mouthful of feathers. He has already injured one hen to the point where she is not able to walk. We have her in the house now to recuperate; she's been limping around since the middle of December. Tonight he waited for one of my small legbar hens to go to the floor of the coop to eat. He pounced on her and did his business, but then would not get off. He stayed on her for a very long time, and if she tried to move he would peck her very hard in the back of the head until she laid her head back on the floor. I was just about to go in and rescue her when the other rooster flew off the roost and attacked the younger rooster. I'm wondering if this is a phase he is going through, or is this his "style" and something he's always going to do. Will he outgrow this? I wanted to keep him for breed, but I really can't risk him injuring any more of my laying hens. Does anyone have any experience with this kind of problem? I could lock him in our quarantine coop until he matures a little more, but I don't think putting him in solitary confinement will teach him manners. Any suggestions?
