Hi,
yes, or Doc is an Avian vet. He is lossing feathers now for about 3 weeks. At first there was a great loss. 10-15 feather, grey ones large and little,
almost all Tail feathers ( he is getting new ones now) and so far 3 wing feathers. He is not baldy at any places but not looking as normal. His diet is
Mikes mash, Fruits and vetagbles in the morning, in the afternoon normal parrot food, containing sunflower seeds, and all sorts of corn. He is not chewing his feather or plucking. Unfortunately he not bahting regularly and he hates being sprayed. We bought a humifyer. apparently he spent 6 days with the vet. His mate Kikki too. We keep him in the living room so it is warm. 22 degrees Celsius. When he spent his time at the vet it was much colder. ( around 10 degrees Celsius)Could this be the course. She has not got a cold, eating fine.
