We have two molting hens, one who is almost grown-in and an EE that is missing about 30% of her feathers and they're just beginning to grow in as pin feathers, so pretty much has naked shoulders and parts of neck and back. Tonight and tomorrow we are expecting lows of 7 and highs of 17 degrees. We have always had an unheated, well-ventilated coop and have never had any problems or frostbite. They have heated water but are otherwise "natural". Do we need to do anything for her like bring her inside tonight? I don't want to stress her more by moving her but I don't want her to be too chilly. Thoughts?
