I asked a local TSC employee about their birds. He said they all try to get them from the closest hatchery. The employees are told to read the books they sell for how to care for them. No one ever checks to see if they do! The only knowledge most of them have is from the books they might read. I did meet a guy who did have some firsthand knowledge on chicks. But the stores usually just get a mixture of what ever the hatchery has. No real sayso. it's cheaper for them to just buy what ever is on sale. So you might get lucky. Its just a gamble.
Good Luck and God Bless!
