Not sure, but the TS chickens may be MRNA vaxxed. Bill Gates is already talking about vaxxing cows with MRNA technology. Chickens are now being inoculated for avian bird flu. Good luck getting a source of pure protein. Oh ya, Purina foods were causing chickens to not lay eggs as well as Pride Ckicken Feed from tractor supply. Just some of what I've heard in the farming community. Take it for what it's worth.
