I recently got a year old rooster. The man who gave him to me said he was completely non aggressive. I recently saw on another chicken group I am on that his wife said he was aggressive and that the other two roosters were aggressive as well. I've only have had him for a couple days and haven't had any problems with him so far. However I want to make sure nothing starts. Is there a way I can keep the rooster thinking I'm the head of the flock.
