Thank you WV it was a really great B-day!
The flaky on this one is just reflection from the light. I'm still second guessing the other one. I have hatched 4 others just like it. The first one is all black so far. Looks like a Black Wyanodtte with some yellowing on the feet.
I've got a couple new Sebrights that have that look, I think it wears off as they feather in, so I was curious.
I'm thinking on mine, it's from different pullets. Wish I could tell their eggs apart
