I have a flock of 11 chickens, they are about 9 months old and this is my first time raising them. I have one rooster, Eagle, and lately he has become a pain. He was never aggressive at all with any of the people, but now he seems to have this desire to be the ultimate protector of the flock. I've been bitten twice now, but only when i'm actually handling one of the hens. he doesn't squawk or raise his hackles, he just comes up and bites me. I've kicked him quite a few times now because it's getting really irritating. My current problem is that although he doesn't hurt me, i have a 2 year old sister who loves to grab the chickens by the tail and snuggle with them. I cannot allow Eagle to peck her and scratch her. But i don't want to have to chop him if he's just being a rooster. The only other variable here is that when he sees anyone other than me (which isnt often) he will follow them around the run and when they try to come in he'll try to attack them. So what do you think I should do? Is he mean, or is this just how a rooster is supposed to be?
