I have a rooster with very heavy foot feathering and a few weeks ago he broke a blood feather from flying into something. We seperated him out until it healed and put him back. A few days later one was broken on each foot, which seemed like an odd coincidence since he has never broken any feathers on his feet in the past, which led me to think that one of the girls had pecked his feet. So we seperated him out again and put blue kote on both his feet. Everything was fine for a week, then another one was broken, and his toe was also pecked next to the broken feather. So again, he went into isolation. He had quite a few new foot feathers growing in so I wanted to give them some time to grow in, hoping that would fix the issue. During this whole time he's been in a seperate cage area in the run, so they can all still be together. He gets very stressed away from his girls but he does fine when he's in the cage in the run. Every night we've been letting him out in the evening with no issues, although I did notice one of our easter eggers who is lowest in the pecking order, seemed fixated on watching his feet when he walked, following him around. Pretty much all his new feathers except for a few are pretty grown in, so I let him out with the girls this morning so I could supervise. Everything was fine for about a half hour, then the EE started lightly pecking at his foot feathers, trying to pull pieces off. She got a couple pieces off but just dropped them, did not eat them. And then she honed in on one spot and she started trying to get at it (all the while I'm trying to get her out of the way so I can pick him up) but she grabbed onto the new little feather and broke it open, and he starts bleeding everywhere. I cleaned him up and back into isolation. I'm confused as to why this is happening. He is not our only feather footed chicken, but he is the only one who is getting his foot feathers pecked. Our EE seems very attracted to the new feathers, but I don't even know how she is seeing them underneath all of the other feathers. Suggestions on what I should do? I need to let his foot heal back up before I put him back with the girls, but I'm thinking of trying to isolate the problem EE and see if that fixes the issue. But any other ideas? I've not really had much pecking issues in the past, but this girl seems persistent.
