He would need a pure bred hen to sell purebred chicks.
Camping, dedicated breeders don't sell their sub standard chicks because they are trying to keep quality and prices higher.
Most breeds were excepted by APA in one color. Breeders decided they wanted other colors, bred chickens in that color and petitioned APA to accept those colors, too.
Getting breeds and different colored varieties accepted by APA is a long arduous road. The breeders working on the new breed or color variety have to be members of APA. Someone has to write the SOP for the breed, APA does not do this. The breed must be represented at APA sanctioned shows for a minimum of 5 years (I think). After this time, APA decides whether the proposed SOP is acceptable. And finally the breed or color variety has to breed true to meet qualifications for APA.
Unaccepted color varieties of accepted breeds are referred to as "project" colors.
I hope all of this made sense.
YES!! Believe it or not, that's what I was trying to say.
I know that papabrooder sells his project birds. I'm not going to be the person storming those beaches, but I will cheer on others who do.
