Hi and welcome. First question, do you have a rooster. If you do it might be from him mating her. Most of mine are missing feathers on eash side of their tails, it's where the rooster grabs them and hangs on to mate. If you do not have a rooster it could be feather pecking, keep putting the spray on her. If it gets worse you need to seperate her for awhile to heal.
