Seems pecking is fairly common - but it needs to stop! I have two one year old Orpington hens and a two year old rooster. Since the really cold temperatures/freezing and ice rain, I've keep a heat lamp on in the coop 24/7, and some days I don't let them out in the run. Just feed and water in the coop. Plenty of room, best of layena food, added greens (kale, cabbage, greens) and raw shelled sunflower seeds for protein - but one of my girls is stripping all the feathers off the other.
I think it's a combination of boredom, and "pecking" order. Of course it's my favorite that's getting abused.
I tried Vicks, then went to "peck-no-more" which is just a syrupy form of menthol. Pecking has gotten worse and now I'm seeing blood. I think separation is needed. Do I just separate the offender in the coop /chicken wire, or should I create a visual plywood block, or put her in the garage for awhile(how long?) my rooster is very protective of his girls.
Any recommendations/suggestions appreciated.
