I have 26 Buff Orpington hens and one rooster. They just started laying the first week in January. We turned an old corn crib on our property into the coop. It measures 30x8 and we sided the whole thing with some left over siding we found in the garage and old windows and a storm door on one end for light. The top of the coop has a tin roof and open wire for about a 2 feet at the top. When it began to snow here we put 2 heat lamps in and they are on all the time. The more I read about heat lamps, the less I am sure that this was a good thing to do. Any input on the heat lamps would be greatly appreciated. About a month ago we had a lot of rain. Because it was so windy the rain blew right into the the coop and drenched the poor girls and all of the bedding. We quickly got a tarp put up at the top so they were no longer getting wet, but the bedding was soggy. It froze very shortly after and we are unable to turn it over. Now it is just one solid piece of wood chip, poopy dirt mess. I'm thinking that I should just put more shavings over it, but wanted to ask if there is anything else I should do. Now, after all that, the girls started laying and don't use their nesting boxes. They are giving us about 8-10 eggs per day. They were all very healthy and seemed to be doing very well until this last week. We noticed that around 7-8 of the birds had feathers that had been plucked off their backs. Broken off and some were bleeding. We thought maybe our one rooster may be doing it, but today he had the same. We have been checking for lice or mites but haven't seen any. I'm wondering if it could be a protien deficiency, even if we are giving them a high protien feed. It has been very, very cold here the last few weeks. Or could it be boredom? They have an old ladder, lots of 1x2 perches that rest between blocks and some boxes in the coop. I don't know what else I could do to stop the behavior. Again, any advise would be great.
