We have 9 buff orps doing the same thing here in Kentucky winter. They have adequate coop and nice sized sanded pen. I did switch them from 16% organic layer back to their 18% grower about a month and a half ago when I noticed one hen losing a lot of feathers. I thought they might be feather picking from not enough protein. Especially since the weather had been wet and cold, and they weren’t out in their tractor regularly to get bugs and worms. I had also been giving them a cup and a half of scratch on days below freezing. In addition, i did a major coop clean ( even though I clean it regularly twice a month), used organic spray for mites in coop and on hens in case they were picking feathers because of cooties. Started putting Durvet’s vitamin supplement in their water 4 or 5 times a week in case they were vitamin A deficient. Also started giving them a can of mackerel mixed with their feed twice per week for extra vitamin A and protein. Started giving my balding hen Rooster Booster Cell every day for a week, then 3 times a week, then once per week. Note that I never really witnessed more than an occasional aggressive feather pull. My hen recovered, grew back her feathers, and things seemed to get back to normal for about 3 weeks. However, I have had feathers all over the pen for the past week now and they seem to be coming from most of my hens…vent area and around legs. We have had a lot of cold, dry weather, and they have been dusting a lot. Every time they do, I see more feathers. They are laying average of 3-4 eggs daily, some days even 5 or 6, despite winter light and conditions. They are active and seem happy. I have seen them occasionally picking each other’s butt feathers, but not anything out of the ordinary. I sprayed them all with Stop That Pecking spray earlier today. The only other thing I can think of is that they are bored or stressed by the recent weather extremes here. They ignore mirrors and toys unless the toys are food related. Food related toys result in competition and aggressive pecking

They do enjoy the occasional head of cabbage, lettuce, etc. when placed in 2 separate hangers. It is hard to keep them entertained without introducing more food

. I have never raised chickens on my own before. Just helped Granny. Could they just be molting early?
