I have three young cockerels. 1 is about 7 months 2 are three months. I noticed the 2 fighting when they were about 9 weeks but i haven't seen them do it in a long time so i think they got it worked out. I saw the 7 month old and one of the 3 month olds fighting a few days ago so i grabbed the 3 month old because i thought he might kill the 7 month old( he is a production red and is much bigger then the 7 month old). They keep running at each other so i usually separate them. Should i keep separating them or let them work it out?
