I think many respectable, well known, and award winning breeders sell chicks and/or eggs. Many people have gotten their start with Marans because of the hard work and generosity of Bev Davis and others.
Over on the Ameraucana breed forum, most if not all of the top breeders (Smith, Blehm, our own pips and peeps) sell eggs and/or chicks. It does help offset the costs of breeding, but I believe they do it for the love
and development of the breed. The more people working on perfecting and improving conformation and egg color is of benefit to the future generations of breeds, particularly those that are rare, or are still works in progress.
As a buyer, I would only want to buy eggs or chicks for their future potential, because I know that as a seller, I would never sell my best birds. If someone asks me about buying adult breeders I will tell them that I only sell
my adult "culls" to be used as layers, but that eggs hold the promise of birds I haven't haven't a chance to choose for myself. As a buyer of eggs, I have hatched and raised some awesome birds that would have never made it out of a breeders flock.
So perhaps when you are at the show you should check out those birds for sale, and if you see some that you like and conform to standards, ask if they have hatching eggs available. This is just my opinion, but I'll bet that the birds that they left at home, or that are on Championship Row and are not for sale, will give you the best chance at the best quality. Plus, you won't have to quarantine
