This is Bilbo, he is a Splash Ameraucana and he is my only roo. I got him about 4 months ago and since the day I got him he has been really sweet and he has kept his distance away from everyone(except the hens) Then, about a month ago, he started getting nasty and flaring his neck or stalking everyone. We have been picking him up after he does this or holding him down on the ground for about 20 seconds. Today, I went out to feed some treats to my girls, and he attacked me from behind!! He drew blood too! What should I do?
