    If I heard this right....lots of barring and light color = Roo. Dark = pullet? I have some really dark ones with almost no White barring at 3 weeks of age...Pullets? and Two who I believe by now are hopelessly roos as they are very light and developing combs. Thanks!

    Sounds like you have it just right. Barring is a sex linked gene and the females only receive one barring gene while the males receive two. Hence the males being lighter with more barring and the females darker.

    Also, when first hatched they can often be told apart by the size of the white dot on the head.

    How can you tell which is which by the size of the dot?
