I recently got a I'm guessing young roo about 3 weeks ago and my girls who are 16-20 weeks old are not happy with him. 3 have just begun to lay eggs about 2 weeks ago. I have 3 naked necks, 2 barred rocks, and 1golden sex linked. All of my girls except for one of the naked necks attacks him. He is an ameraucana roo and he just runs away although the girls succeed in plucking his feathers before he gets away. I have him separated in a dog kennel where the girls can see him so they will get used to him, but when I let them free range, they still attack him. I don't know if its because the lady I got him from had him in a pen with 4 other roos and he might be the submissive one or if because he is still young. Is there anyway I can get my girls to play nice with him?
