So from a breeder's viewpoint, are most hatcheries pretty much the same? Is there anything to be said for them (hatcheries)?
Yes please
I think within a range, most of the big hatcheries are similar, yes. Some have been around longer than others, but as Wendell said, they breed for high production and early first lay, and for anyone just wanting eggs for the family there is nothing wrong with buying from them. The chicks are usually healthy, and you can buy sexed chicks. I have an order in with McMurray for chicks at the end of January, just pullets, which I plan to raise for a few weeks and then sell once they don't need artificial heat - in other words, when they are fully feathered.
When you buy from someone breeding toward the American Poultry Association Standard Of Perfection (APA SOP) you will see differences, and often that includes a longer time before a pullet matures and begins to lay. Usually those breeders sell straight run chicks only, so you can expect about 50% males. When you want a hen bred to the SOP and can't risk getting males, you can buy juveniles from someone who did buy from a breeder or hatched his/her own chicks and has started culling - deciding which females not to breed. Those are usually available for sale later in the year, when they've grown out enough to start making those decisions. Buying from people who do this helps support their endeavors to breed higher quality birds. Most specialize in only one, two, or three breeds, so if you're after something else this may not be an option. Wendell is specializing in Dominiques; once I get my breeding stock selected next year I will specialize in Speckled Sussex and Colored Leghorns. I had hoped to postpone the leghorns a year, but was reminded by members of another thread that Mr. Urch may not be breeding many more years, and I want his lines.
I buy from both types of places, and as long as you understand what you are buying there is nothing wrong with either. In the case of Duane Urch, he has been breeding a long time and has lines of some breeds that are decades old. I happen to love Sussex and Leghorns, each for their own reasons, and want to try my hand at breeding toward the SOP. I live in a rural area, so I am lucky enough to have this option.
