Permanent loss of flight feathers in cockatoo
A friend of mine has an umbrella cockatoo that has permanently lost her flight feathers on one wing. He's had her for 4 years (she is 15 years old). Her wing was like that when he got her, and the previous owners were not forthcoming about the issue. The bird has lived in the same vicinity as a lorikeet for the last few years; both have been vet-checked and confirmed to be healthy. He wants me to bird-sit the cockatoo and lorikeet while he's on vacation, but if they are carriers of something like PBFD, I don't want to expose my conures, lovebird, and Meyers to them. I would appreciate some advice on this matter. Thanks!
