A few was ago, we found one of our 7-8 mo old chickens to have lost most of her feathers around her vent and a white coating. We decided it was a fungal infection, gave her a bath and applied anti fungal cream. She still doesn't have feathers and a slight film still but is acting fine. On Friday, I noticed one of the other chickens to have some stuck together feathers near her vent...matted...no white film but looked like some dried blood. We had an extra large egg that day with bloodied feathers on it. The next day, the chicken was dead. Today I went out and another chicken has bright red feathers around her vent and drops of blood in the coop. So far she is still alive but I'm concerned she isnt going to make it. I'm at a loss...is this all related? Do we have a parasite? Help! Thanks!
