Hi. I have a 5+ year old canary (Colin) who has developed feather cysts over the last year.

We have had a couple removed by the vet, but following his recent moult, the canary not the vet, he now has loads of them.
I don't think removing them is going to solve anything and will probably just be v. painful.
Any thoughts? I guess his quality of life will deteriorate and then we'll have to make a dreaded decision.
