Short background story. I started out with 6 chicks. Chicken math went wrong. I eneded up 5 cocks and one hen. I purchased 4 icelandics, was told they were all hens. Ended up with 2 and 2. Had to cull 5. At this point I had 2 cocks and 3 hens. Purchased 4 more hens. 2 Americanas and 2 Easter Eggers. So sitting at 2 cocks and 7 hens. Neighbour doesn't keep over winter, got 4 more hens. 3 RIR and 1 leghorn. I'm pretty much a pro at the introduction of newbies to the flock by now. 2 weeks goes by and my rock barred attacks the leghorn causing a nasty head wound. He also starts attacking my 2 little girls. In the stew point he goes. End result is 1 roo and 11 hens. The leghorn is completely healed. 3 weeks later my iclenadic roo attacks the leghorn again. She becomes a house chicken for a month, completely healed. Wanted to get her out before winter. She was doing good until he wants again attacks her. I cage her in a large dog kennel within the coop. I always make sure she's healed before allowing her to go with flock. But he keeps attacking and causing a severe head wound. Any ideas why he would continue this? I have now not allowed him in the coop and during free range time which is pretty much all day. I keep her in the run with her 3 best hen friends. I would like to breed the icelandics. So I would like to keep him. I would just like to know why he would only be aggressive to this one hen. He is a gentlemen to all the others. Brings them treats, alerts to Predators, allows my kids to pet him, etc. Would the original attack by the rock barred on her cause him to attack her? Is it because she looks different from the rest?
