Novice here. New to raising chickens and wanted to get some for egg production. We bought 6 "production layers" from tractor supply about 10-11 weeks ago. They were little yellow walking tennis balls. They grew rather quickly and now are really big. They are white with red beards similar to leghorns, but are really big and fat. A friend was at my house yesterday said they look more like broilers than his layers, although he does not have any chickens of this color. He is 1 years into it and was not 100% sure he was correct. Can anyone tell me if it is normal for layer chickens to get "really big"? How can I tell if we were sold meat chickens instead of layers?
