Greetings! My silky bantam has extremely dry, white flaking skin/ dander. She's losing feathers, in addition - she's lethargic, not moving around much and no appetite to eat or drink. Overall - not good signs. Help?! Any suggestions? I used D.E. powder for any chance of mites. She's isolated from the other hens. I've been giving her electrolytes & water via syringe. However, so far no improvement. Her skin has white flakes everywhere (looks like dandruff). Any feedback = greatly appreciated! She's a really sweet hen. Thanks!
