Canary plucking feather and completely lost tail
(Temple, TX, USA)
Our crested red factor canary all of a sudden began to pluck his feathers and both sides are raw (within a few days). He has also lost all his tail feathers. He started out by sitting in his gravel dish now he sits there all the time. I came home and found fluffy feathers all over the floor. He hasn't molted since we've had him (he is under a year old) but our yellow canary has never had this problem even in molt season. Do I need to take him to a vet or what is he lacking?
I supplement a couple times a week with apple and lettuce and he always has plenty of water. He is a beautiful singer but hasn't sang for a few days either.
