I would choose getting chicks directly from hatcheries and breeders rather than Tractor Supply. The chicks at Tractor Supply come from Hoover's Hatchery and sometimes Ideal Poultry. My experience with Tractor Supply is that they constantly get their birds mixed up. I have seen Cornish Cross in the Assorted Bantam bin, I have seen ducks in the Brahma bin, random mixed breeds in random bins, and more. It's crazy with the way Tractor Supply doesn't know their stuff. Once, I was getting chicks out of the Unsexed Assorted Bantam bin and asked a worker there if they knew what breeds these chicks were. They replied, "Unsexed." A lot of my chickens come from Tractor Supply and some of them actually look great for the breed, but some are absolutely not what they are supposed to look like.
