One of my 10 month olds is going through what appears to be a hard molt. She quit laying about a week & 1/2 ago and there were some feathers about. Yesterday I found 90 some, today 130 some and that was just in the coop, who knows how many in the run. I am surprised this is happening because she has continuous artificial light. I don't like having to do that but I started it a couple months ago when temps became so frigid to help w/ heat (a soft white 100 watt incandescent bulb). I am concerned because I live in Michigan and they are only in an uninsulated tractor coop though the run is wrapped in plastic. Also I only have one other chicken and they don't cuddle. We have been covered in deep snow all Winter. Most of our Winter it has been teens in the day and single digits at night w/ no change foreseen in the near future. I give her additional protein everyday for feather growth and them a handful of cracked corn at night for heat. What else should I/ can I do to help? Can she survive this?
