3 yr old buff orpington roo was attacked last summer by a fox but recovered. Now he is noticed to be very lethargic, laying around, and with patches of feather loss. I brought him in to see what's happening and found tiny yellowish larve(head of a pin size) and all remaining feathers have lint like clumps where the shaft meets the body. Many feathers pull out when I try to pick it off. Would appreciate any input. He has isolated himself in the coop and I will treat him if I can find the cure.
