I had an Ameraucana rooster for 3 years and he was only aggressive towards me not my kids or my husband, but my kids are 15 years and older. I got rid of him due to me finding out that I am not supposed to have roosters. The farm I gave him to, he cowered quickly to another young, but aggressive rooster. My leghorn mix between a leghorn hen and the Ameraucana rooster was the best except for his big comb that almost covered one of his eyes. He was the never the alpha rooster and he never came at anyone plus he loved his hens. I hand fed him as he struggled as a chick so not sure if that had anything to do with it, but he was the sweetest and best rooster. I gave him away to a beautiful farm and he has 6 lovely hens. My last rooster was a mix between a buff orpington and the Ameraucana rooster. He tried at times to herd me, but would stop and never tried to attack me like the Ameraucana. He went to a new farm with one of his sister hens that grew up with him and 2 other roosters because none of the hens would accept her. I had to Cull other roosters who came at my kids and different ones are just mean even if you don't interact with them as we found that out with the last bunch of chicks we raised. The mixed roosters that we held and gave more attention to were better behaved except for Luna the Ameraucana who hated me. So sad that I can't raise any more chicks as I had to get a permit and can only have 6 hens no roosters. Wish I could have given you one of mine that were "good," as I was lucky to find all 3 a home including Luna the mean one.
