Hi. I have 3 Dom hens, 6 mixed pullets, and 1 Buff cockeral (about 3 mos.) I plan to buy 1 Rhode Island Red cockeral and 2 pullets. Since the cockerals are young and will have time to adjust to one another, will they be okay together? Or, will this be a mistake? I don't want alot of fighting. They will all share the same coop.
