    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.

    I have no clue because I thought a barred hen would pass on barring to her male offspring but not the pullets. And if you had a barred roo and a red pullet, you would get barred pullet offspring but not barred roo offspring.

    I am hoping someone can clarify for me.

    So I quickly tried the chicken genetic calculator and found that a barred roo will pass on all barred offspring when bred to a unicolor hen. A unicolor roo and a barred hen will only pass on the barring to the roo offspring. So I guess to get sex link you need barred hen and other color roo, that way you know that all barred offspring will be male, all non barred offspring will be female.

    Hope someone comes along and clarifys.

    I have a white pen pictured below, the hens are barred and the roo is white. I just hatched my first chick and it is dark blue, possible barred so I would say it is a roo chick.
