It has been cold here off and on, last night down to 17 degrees. About half of my flock decided to molt at the end of November, I don't know what the delay was this year, no artificial light used. I have several of the molting hens that are literally missing half of their feathers I could tell this morning they were freezing. I hope there new feathers grow in quickly I don't know what I can do for them. I am feeding dry cat food twice a day to give them extra protein to help in a quicker development of new feathers.
