sorry i can't figure out how to phrase my question to make a good search term =/ are there traits associated with being passed from the roo VS passed from the hen? for example, i know to make a sexlinked chick, you might use a red roo and a barred hen, but not the other way around. why? does meatiness come more from the roo or the hen, or both? what about egg laying ability? etc. any info or links would be much appreciated! all i can find online so far has to do with coloring, which is interesting, but not really what i'm looking for.
