These are my guesses:
1. It's mother was red, so maybe a Rhode Island Red or New Hampshire Red?
2. It's mother was a Cochin?
3. I know cochins are sometimes frizzles, so maybe it's mother was a Frizzle Cochin?
4. Splash or blue Cochin mother
5. I think this one is not a mix. Easter Egger?
6. It is hard to tell from the picture, but I would guess Black Australorp mix.
I do not know much about genetics, but those are my guesses. Did I get any of them correct?
