Ask the breeder to kindly send you photos of the parent stock. That's what I would recommend.
If the breeer is reputable and has a track record at ABA and/or APA events, that too would be helpful.
OK. Birds of quality for exhibition do not come from hatcheries, but from fanciers of the birds who breed them for this purpose.
However, if you wish to "show" the bird at a local fair or 4H, which features you and your showmanship, then it does not matter.
It would be you being judged, not the bird so much. Hope that helps.
