I have a chicken that is about 1/12 years old. A Rhode Island Red and she injured on of her legs yesterday. I brought her in to isolate her and keep her off the leg. She just let loose with feathers like I have never seen. She has never molted like that before and I was wondering if the shock of her injury could cause them to drop an inordinate amount of feathers all at once. If not, what could it be. They all got wormed with Wazine last week but I can't think of any connection to that. Any help or suggestions would greatly be appreciated. Thanks
