I have a Bo cockerel who will be five months old in a couple of weeks. At first I thought he didn't like my pink pants when he first started doing it. When I first go into the chicken house he will go over and peck my pant leg and grab onto it. He has been doing this for 3 days in a row. Is he starting to be aggressive towards me? If he is then has nominated himself to be the first to go out of my 2 (maybe 3) BO cockerels.
