Don't buy from them. I don't like doing business with ignorant people. Buy from Rivertown Feed, which gets birds from Privett. You can order what you want through them if you want quantity less than 25. At least they know what they have and where it came from. Tractor Supply just puts local feed stores and breeders under the burden of doing less business. TS is a corporate chain carrying a lot of Chinese products and their staff doesn't know the difference between a lemon or a lime.
Definitely won't be buying chicks from them again.
