Erm, you can do it yourself. Theres one method which is easy, but hard emotionally. Just pull 3 or so feathers out of the birds chest. Yea, hard emotionally! They can test off the bits of skin left on a pulled feather.
OR (how we do it)
Take a blood card in with you when you do nails. We clip em ourselves, but I'm sure you could take one with you. Just get blood from a slightly short clipped toenail on the card..then mail it.
For disease testing it gets harder because you need to be sure your getting clean samples with no contamination, but with dna its pretty simple
