Right now, in front of my eyes my sweet rooster killed one of my one year old hens This is their living arrangement: I have separated the "friendly, kind, gentle (about 3 years old)" rooster and the two older hens for one year. They formed their own alliance. Separate coops for sleeping. They are separated from the two, one- year -old hens, of which, one of the older girls did not like. They all free range on 35 acres in separate groups. Two- one year hens in one group and the other group, rooster, two- three year old hens and one of the one- year- old hens that the group accepted as one of their own. I noticed fussing this morning between the aggressive older girl and the submissive one year old hen, after I opened their pens. So i kept an eye on them. Quickly, the rooster starts chasing the submissive one- year -old hen(from the other group) and i thought he was trying to mate. I didnt have a good feeling because he seemed so relentless, so i quickly followed to catch him standing on her head behind some shrubbery next to the pen. Done. Gone. That fast. So i found the other one- year- old hen who was her friend and promptly placed her back in her pen alone and protected from the rooster and the aggressive girl. What to do next?
