It's the vet that checks for all diseases. Breeders don't have the testing material to do all tests. It's called a *well check* and if a problem is found, the buyer is entitled to a refund, a warranty, or a guarantee and the bird has to be fully weaned in order for a vet to perform every internal test that's required in order for a bird to get an approved bill of health. Nor do breeders have access to all the labratories which perform those tests. Either the breeder pays for that test ( which is included in the purchase price) or the buyer pays for that test depending upon the bill of sale contract.<br><br>Post edited by: Dave007, at: 2008/12/29 21:50
