Breed and Gender Help? 2 Chicks

[Shadow3]

The chick is not a Speckled Sussex.
Specific details:
Speckled Sussex have single combs, and that chick has a pea comb.
Speckled Sussex have white feet, and that chick has green feet.


I would also guess Easter Egger because of the green legs and pea comb.
Or it could be some kind of backyard mix.

Super interesting! Love the detailed explanation. Thank you so much!
