Paint? BYM cockerel colour, plus Breeding

[Canadian Wind]

I got this boy about 4 weeks ago, estimating his age around 9-10 weeks. He's a BYM and I purchased him with what I am assuming are his siblings, who are all black.

Part 1: Trying to figure out his colour.

Part 2: I want to breed him (eventually!) to a Black Sex Link BYM that I hatched out. Her parents were the reddest red rooster I have ever seen (BYM) and a Blue Barred hen (also BYM). I can't put either of them in the genetics calculator but ignoring recessives what would I get as offspring?

Thanks!

Personally, I would expect more black and white birds, with a bit of red leakage on male's, maybe on females too

I think he has some pattern in black-and-silver, not paint.

The Silver gene turns red/gold shades into white.

Paint involves Dominant White turning black into white but missing a few bits. For the amount of black he has, and the way it is distributed, I do not think he has that.

Ignoring recessives, I would expect a blue hen with that rooster to produce blue chicks and black chicks in about equal numbers.

But if her father was red, she's only got on E gene (Extended Black), so only half of her chicks inherit that. She also has e+ or E^Wh or something of the sort, which will be inherited by the other half of her chicks.

If I consider that recessive gene at the e-locus, only half of her chicks will be blue or black, and the other half will have some pattern of silver and black (like the rooster) or silver and blue.

The hen must have the gold gene (inherited from her father), and the rooster is likely pure for the Silver gene. So daughters will be silver, and sons will show silver but carry gold. Either sex may have some red or gold leakage, but it is much more likely in sons than in daughters. They may have yellowish feathers instead of a clean white color, and they are likely to show red patches in their shoulder areas as they grow up.

I agree, except the blue gene (from the proposed mother) will turn the black into blue on half of the chicks. Oops. Never mind about the blue, I was mis-reading the original post. The mother does not have the blue gene.

Thanks! But the proposed mom isn't blue, HER mom was and didn't pass that gene along to her daughter (the BLUE gene I understand, lol!).

The potential babies sound lovely! Too bad the males will be the nicer ones. Why can't males just get along??!!! LOL!

Oops, missed that.

In that case, half of chicks black, the other half black-and-silver, with possible leakage in any of them but especially the males.

And now to wait until they mature enough to give me eggs. And see what kind of recessives they have (if compatible)!
