Just don't forget when criticizing the choices of other backyard chicken farmers; it can be very difficult for them to find breeders of the heritage chicken breeds they desire, especially ones who are willing to sell to them. It is particularly difficult if they don't wish to become breeders themselves, or if they only want to breed for their own use.
A look at this very thread disproves that. If you are dedicated to having a certain breed it is a simple matter of effort and time to find a quality breeder. A sense of entitlement won't get folks very far I agree on that point though.
