I've gotten chicks from McMurray a lot and they have awesome chicks. Their birds are for the most part healthy, friendly, and good producers (though I mostly keep them as pets and a hobby, so I don't keep a record of their egg laying or anything).
If you live in the western half of the states you could try one of the hatcheries over there. They have some great chicks. I've bought from Cackle and all the chicks except one did wonderfully.
At this time of year some of the breeds aren't available at many of the hatcheries. If you want specific breeds you may want to wait until next spring (that's what I have to do).
I hope you can find some wonderful chicks! Best of luck!
