I'm not exactly sure what type of "breed" production reds are. I'm thinking they are a mixture of red-feathered breeds that lay brown eggs, such as Rhode Island Red, New Hampshire Red, or Red Sexlink (Red Sexlinks are a cross between a Rhode Island Red cock and a White Leghorn hen, but one of mine looked more like a New Hampshire). Perhaps they are hybrids of those breeds. From my experience, all of these breeds are very nice. My friend has Production Reds, and to me, they look like Red Sexlinks and New Hampshires, but some of the pictures you guys posted looked like they had a Buff variety of some breed mixed in, maybe Orpington or Plymouth Rock.
