We have 15 chickens and have had them since chicks and they are now about a year old. We have never had pecking issues before. Now there are some that are being pecked and have raw backs and behinds. It is winter here so they have been staying in the coop more (they have a coop with a heat lamp and an outside covered run area as well). We had been letting them free range when we were around but haven't in awhile due to the cold and snow. Our first question is what do we do about the pecking-is there anyway to stop it? Second question is how do we treat the raw backs and behinds that have been pecked? They are very sore. We know people say to separate the chickens but there are probably about 5 chickens that have raw areas, so would we remove them from the coop and put them together or should they be individually separated so they are alone? Separation of any of them will be difficult to do. Thank you so much for your help!
