I picked up a dozen chickens from tractor supply Company earlier this week. One was labeled as straight run, the rest were labeled only as pullets. Tractor supply Company got them from the hatchery with only those labels. I am curiousto find out what breed of chicken they are. There could be multiple breeds.any ideas as to what breeds they could be? Also, any idea on if the straight run is a rooster or a pullet? And what breed?
