Oh I just thought of something more likely. He probably is dominant white, blue, and barred.
Oftentimes barring can be seen on dominant white but if you had blue in addition to that it would be hard to see.
I would expect to see barring on his orangey feathers but that doesn’t always occur.

I know the exact parents of one of them, since it has feathered feet and only one hen in my flock has feathered feet and I only had one roo at the time.

That definitely narrows down the options!

I was thinking the same thing.

He probably is dominant white, blue, and barred.

He could be blue or splash, along with barring and dominant white, except that we aren't seeing the barring on his orange feathers. I don't know if blue or splash would make a difference in how barring shows on that part of him.

I have no trouble recognizing barring on black chickens, but it gets much harder on other colors!

I have had several barred chicks and a single Blue Chick pop up in my mutt flock when I have never had either of those colors in that flock before.

For the genes I suspect he has, I would expect about half of his chicks to be white, and about half of his chicks to have barring. But that would mean visible barring on only 1/4 of the chicks (because it would not be recognized on the white ones.) And depending on what other colors are involved, the barring might be hard to see on some of the non-white ones too.

The roo's mom was a dominant white leghorn. His dad was what I think was a Phoenix x golden laced polish. The hen's mom was a white leghorn x mixed breed game that was golduckwingish colored.

The rooster might have gotten barring from his White Leghorn mother. That would explain why you never saw barring before: the barring gene needed to appear in a chicken that was not white, before you could tell it was there.

Thanks, that narrows things down a bit. I wonder why I haven't gotten any other blue chicks out of the 35 chicks Ive hatched from that flock.

Is this a blue chick or a barred one or both?
Perhaps your rooster is actually splash rather than dominant white.
Maybe splash hides barring even better than blue.

Just blue with some gold leakage around the front.

This thread is for oddballs that have popped up during breedings, whether it's a weird color chick/Adult bird, funky comb, toes(Polydactly), egg color, etc...

Here's one of mine to start.

Big Fatty, she's pure Malay, but doesn't look like it, she's just odd. Both parents are full sized, she hatched out of a Jumbo Egg.

She is a pretty girl

Can just be the odds. I had a blue male and every single chick he fathered that had a bbs mother ended up either blue or splash with only one exception of a black daughter. Out of dozens, she was the only black he fathered

Interesting. I just sold the roo, but have a hen sitting on eggs that might be fathered by him.

If that rooster is the one with blue, and if he has just one blue gene, then he should give blue to about half of his chicks. But you can't see blue on a white chick, so that would mean half of the "blues" are invisible.

Have you gotten any chicks that are primarily red or gold? If so, maybe check them to see if any "black" areas are actually blue. That is another way for blue to hide, because it only affects black and not the red/gold shades (or at least it doesn't affect red/gold enough to be obvious in a case like this. Some people say it has a small effect on them.)

I had one that hatched completely black but grew a lot of gold leakage. The black areas were just black. I did have a lot of white chicks this year...

You showed a picture of a black hen.
What other color hens were involved?

Yes, lots of white chicks means lots of chicks that cannot show whether they have barring or blue.
