Hello ! I have chickens that am assuming have been over mounted by rooster. They have little to no feathers left on their backs. I bought them saddles to protect their backs and hopefully allow feathers to grow back .. accept it seems to have made it worse, now the feathers will not grow back at all and their shoulders are all getting bare and some are missing tail feathers . I swapped out saddles to some of the worse hens and now they are getting sunburned .. I am not sure how to premote new feather growth and keep saddles on for protection . I have saddles with shoulder protection on the way but I think the saddles are preventing feather re-growth... is getting rid of roosters my only option or attempting separation somehow ? any ideas would be appreciated.
