They are Ideal's production strain of a RIR and a little bit of New Hampshire red in the background.They are a chestnut red very similar to RIR's and are excellent large egg layers.I have several and they are great.Some hatchery's have a bird called a Cherry Egger which is basically the same thing.
They are a hybrid chicken I think, they aren't just straight RIRs. Other than that I don't know much about them. I do know that Cackle sells them and I recently got a fantastic order from Cackle. If your looking for somewhere to buy from they are really good.
