Hi everyone, I have a 2 year old Golden Wynadotte, that I'm concerned about. In less than a week she's lost at least half of her feathers. She also has runny poop stuck to her butt. A couple of months she also had torn off part of her comb, but that has since healed. She has also stopped laying. The other two hens seem fine. I'm suspecting lice or mites, but would love some advice. I have dusted them for lice in the past and also have a dust bath set up in the coop with kitty litter and Sevin. Is it possible that this is just a normal molt?
