I've had a silkie pullet and what I think is a RIR cockerel together since they were 2 and 5 weeks, now for about two weeks the cockerel is biting me and now really rough on my silkie pullet. Do I need to get rid of him? They are house chickenss with a co-op inside and I let them roam around when I'm home. I don't want him to hurt her but he seems to chase after her a lot! Please give me advice!? Thank y'all!!!
