hormones kicking in later than usual? this type of behavior is mostly seen in a maturing cockerel that is like a teenager very unpredictable when it hits. sometimes once they get used to it they return to their normal behavior but some don't. I just feed to him and let him feed his hens until he settles, usually a good way to do it. but don't let him be a bully either., Chicken jail knocks a lot of the attitude outta them. Also Do not let kids in there unless he is locked up.
