So we were thinking about buying a particular breed from a breeder here in Oklahoma. For this breed is important that the bloodline is true and not mixed. I have been in contact with other breeders out of state, but i would have to pay costly shipping fees. So before committing to the breeder here in Oklahoma (with a slightly higher per bird price than the other breeders), i asked where he obtained the bloodlines. I asked the other breeders, and they didn't hesitate to tell me where they got their bloodlines; but the one here in Oklahoma said he can't disclose that information.
So my question is, why would a (reputable?) breeder not disclose where they obtained their bloodlines for a particular (and desirable by many) breed? Would you buy from this breeder, why or why not? Or does it depend on certain circumstances?
