I just aquired five hens and a rooster. It is starting to get cold in wyoming, and these all but two dont have many feathers on their backs. They are in a insulated temporary coop, I would like to know if their is anything I can do to help then should i apply any thing to help to make them more comfortable. I have a infra red heat light over their roost and they seem comfortable there. Is there any antibiotics , or anything that i could put in their water to make them more healthy. The hens have a device in their beaks to keep them from pulling feathers from each other. I might ad that they are year old hens. I just got them yesterday. [email protected] any help i can get to make sure they are healty thanking you.
