It could be state law that prevents it. That said they're clearly ignoring the well being of these chicks. Especially when they sell the damn tubs they keep them in. Why not set up another brooder?Tractor Supply does stuff like this but won't sell me 2 chicks to add to my existing group of chicks in the brooder. I no longer do business with Tractor Supply.
Anyway, I'd get the authorities involved if the conditions have not improved. The last thing TSC should want is to piss off BYC. We are a force to be reckoned with.
