RIR Hen with a mixed Roo

[16 and me]

I inherited this mixed Rooster, so I know nothing about his genetics. I have 3 broodies that are sitting on eggs. The egg from the RIR in the photo hatched this morning, and the chick is black with a yellow dot on it's head. I understand that this means there's barring in the mix. Would this then be a male? The 3 hens are still sitting on his stock from the following hens:
Blue cochin, Barred Rock, Wellsummer, Ameraucauna, and some other barnyard mixes.
If he has 1 barred gene, what would I expect from his offspring from the hens that are not mixes? Does the male give only 1 gene, meaning it's 50/50 if he gives the barred or not, or will there be barring in all his offspring?

You won't know if this rooster carries barring unless you breed him to non-barred hens and see what his offspring look like (since the barring genetics could be masked by white.)

When crossed to solid colored, non-white females, if all of his chicks are barred, he carries double barring. If some of his chicks are barred, he carries single barring.

Thanks Jenerator! This black chick with the dot on it's head is from the RIR. Does this confirm that he has some barring - either single or double?

The only 2 solid colour hens I'm hatching from are the Blue Cochin and the RIR. 4 in total So I guess it's a small selection from which to test.

Yes, if it's from that cross. Your rooster's offspring can only be single barred because he'll only pass down one copy to each of his offspring (if bred to unbarred females). If any of his chicks aren't barred, he only carries one copy of the barring gene.

Thank you! I actually had no idea he even had barring because it doesn't show in him. Is that because he has dominant? white that has turned his black to white?

Yes. Both dominant white and recessive white will mask barring, and turn black to white. Recessive white will also mask red.

If he produces any white chicks when bred to a colored hen, he carries dominant white. You need 2 copies of recessive white for it to be expressed, so if he was recessive white and bred to a solid color hen, none of his chicks would be white.

Yes, I'd assume he carries dominant white because recessive white would also cover any red leakage. Both dominant white and recessive white will mask barring, and turn black to white.

If he produces any white chicks when bred to a colored hen, he carries dominant white. You need 2 copies of recessive white for it to be expressed, so if he was recessive white and bred to a solid color hen, none of his chicks would be white.

Thank you! You are a wealth of knowledge. With a dozen eggs under the hens, I'll know more in the next few weeks. I need some sort of webinar training on chicken genetics. It's fascinating, but there's so much to learn, and when I try reading the "e+ i/I alleles^ wh b^" language I just get lost lol.
