I rescued two hens from the animal shelter. One looks great (Carla) but the other (Camilla) has been loosing feathers from below her tail to Che chest. They both are eating and drinking just fine. Carla has been giving herself regular dirt baths, but I haven't seen Camilla do it once. She has had poop on her belly from the transport home about a week ago. Carla has brushed hers all off with the dirt baths. I just bathed Camilla and took a photo. So her feathers are all wet. I'm hoping that will help but if there is a possible parasite what should I do? She also has been sneezing the last 4-5 days. I also noticed a metal tag on her wing. The shelter said they were "owner surrender" but the tag is making me think they weren't just backyard chickens.
