I too appreciate that you are thinking of this, it's something I have wished for. unfortunately it seems that there are so many variables that it's hard to nail down. a few years back I was given some advice which seems to hold true to this day, that the best hatchery is the one that is closest to you. the distance and time that the chicks travel seems to be one of the main determiners of outcome. and it gets tricky, because if a hatchery runs out of what you want, it's common practice among some to simply have them shipped from another hatchery, which might be much further away.
I had some bad experiences with mailed eggs and mailed chicks and started asking more questions through the customer service line before ordering my next chicks. I also asked around locally on forums to see who was having good outcomes from which local hatcheries. I was directed to jenks hatchery in OR and so I called them, and low and behold, one of the owners picked up the phone and he was kind enough to spend about 45 minutes explaining many details about the breed of chick I was after, the cornish cross meat bird. for me, the information he gave me was invaluable, that there was a specific line of cornish cross that was much more healthy, happy and chicken like, a much better bird for the back yard producer.
I would highly recommend spending some time, doing some research, asking around locally maybe through your state thread or local forums and once you get a bit knowledgable, call them directly and start asking a few revealing questions like, do you ship from other hatcheries or can I be assured I will get the chicks directly from you?, what is your return policy? and any other questions you want specific to the breed you want. once you find a good hatchery for your location, share your info with others near you. location, location, location seems to be the mantra.
