Thanks for the replies everyone!
I saw that someone said that the aviary should be closed to the public. Wouldn't you want to see where the adults were staying to be sure you weren't funding a facility where the adults are kept in bad conditions? With dogs, I know that it's extremely important to see the parents. Maybe this isn't the case with birds though.
It looks like I have a lot to learn. I've handfed baby birds several times. Successfully I might add. Not a parrot though. I bred cockatiels years ago and handfed the babies. I've handfed parakeets, wild canaries and random wild baby birds that I found when the sanctuary couldn't be reached or couldn't take them. But again, I've never handfed a parrot and I don't know if that is very different from other birds.
KittyKittyKitty said: Good breeders do test the birds, usually several times and at least start immunization.
What tests are done and why do they need to be done several times?
