If you're looking for hatchery birds, I'd second Monroe Farm & Feed. Great selection and they keep their chicks well maintained. I've been to a few places where the conditions are just downright filthy and the birds in very poor shape.
The guy on CL I believe is in Stanwood. I've talked with him and he said he did buy out the hatchery that was over in eastern WA. Phinney was it? Nice guy but he doesn't know much about poultry and is just pretty much a hatchery in it for the $$.
If you do a Google Search for hatcheries, I think you'll find a site that lists all the hatcheries in the USA. It's been a couple of years but I remember seeing it.
Not sure where you are but there was a show last weekend in Monroe and there's a show coming up in April in Stevenson. Shows are great places to get some really nice birds and talk with the actual breeders.
Depending on what you're looking for, either I could help you or point you towards a couple of good breeders. Personally, I have some feedstore/hatchery varieties because I haven't found any breeders yet for them and I use them to keep my customers in eggs when my birds are in the breeding pens. It costs the same to feed a poor looking bird as it does a really good looking bird so I try to get breeder's birds when I can. There were a couple of breeds at the past show that had some production birds being shown and it was a stark visual example of the difference between the two.
Hope that helps.
God Bless,
