delisha, So what you are saying is that Hatcheries are not using their show quality stock (which they most certainly have) to supply you with good quality birds each and every year? Bad choice of words by you in my opinion. These hatcheries wouldnt have survived for as long as they have if they kept breeding bad quality birds with smaller and smaller skinny chests. Something very wrong with your opinion of hatcheries. I myself used a hatchery cock that won a few awards through showing. Culling has been done for centuries and is a tryed and true method to obtaining better quality stock. I have to agree that not all the birds I have acquired through a hatchery are perfect and would only qualify as pet quality. Thats not to say you cant get good birds from a hatchery as you so suggest.
I would seriously doubt hatcheries have show quality stock... if a hatchery advertises show quality, usually those chicks are drop shipped directly from the breeder, not the hatchery. but even then I would say those birds are borderline sq IMO
