Okay, so I know very little about any other chickens except Orpingtons. Are the Cornish Rocks that Tractor Supply has during "Chick Days" the "meatie" birds or are these also good for pets/layers? There was a lady in Tractor Supply yesterday (first time chicken owners) and she was buying Cornish Rocks for her kids for pets, and I thought Cornish Rocks were basically for meat.
