This site is effective for selling birds. Sellers have the right to block buyers who ask a lot of questions and never buy. They're annoying and life is too short. It is always the buyers responsibility to take the bird to the vet not the seller. Most of the birds are well and buyers can see if there's illness by sight from fluff and diarrhea. Expecting sellers to do dna tests on birds are stupid. Buyers asking PetSmart to do dna tests are stupid and should spend their own money on that kind of bull$#*!
