If you are just breeding birds for yourself, for eggs and meat, does it really matter if they are hybrids or crosses? As long as they are producing eggs in quantities you like, and a decent carcass size, does it matter how close they are to SOP for RIR? Do you want to show at some point or sell pure chicks and hatching eggs?
What do you mean you "have to color feed for a look I want"? The deep dark red you see in exhibition RIR isn't achieved by color in the feed, it's through selective breeding.
