I am wondering if my hens' feathers will grow back. I had a ratio of 18 hens to 2 roosters last season which seemed acceptable. Unfortunately my roosters only got with my new hens so it was more like a ratio of 10 to 2. Most of my year old hens now have no feathers on their backs. I recently put my roosters in the freezer but, after about 3 weeks haven't seen any sign of feather regrowth on my hens backs. Is it too soon or after almost a year of no feathers are things too damaged for me to expect regrowth? Does anyone else have experience with this? I'm sick of having homely hens!
