Polyoma

Is Polyomavirus treatable diamond Gould Dame?

Good question. I'm looking on http://www.ladygouldianfinch.com
They have a disinfectant that works for the kill. Still looking ... I can not find anything finches, but this does not mean anything.

If in doubt, call an avian vet and ask. From what I see and can not be cured if he has a bird, they should be kept in a bird house and not only used for breeding. These articles do not talk Hookbill, then check with a veterinarian.
