What do you mean they don't breed true? Every chick I've hatched grew up to look like it's parents in every generation. If that's not breeding true then I don't know what is. Yes we are striving for improvement in areas like color, but that is a different criteria than saying they are not breeding true. I've never hatched anything that looks like a RIR, or a BR, or any other breed other than Cream Legbars from my Cream Legbars, and I've never hatched one I could not tell gender at hatch.
