That's cool if she lays colored eggs! The blue/green shell gene is closely related to a pea comb, and your bird's comb looks like a cross between a pea and a straight, so it's never a sure thing if the blue/green genes came across, also. I love my colored eggs!
You're in the US, so your red bird is a hatchery Rhode Island Red. True, the heritage, high quality Reds are a darker, almost mahogany color, but your bird is very nice for hatchery quality, which is what the majority of us have.
Warrens are a British thing, to my knowledge. Not a US breed.
