Extra chick

[Party_Chicken]

I think you're right about the Wyandotte (rose comb) and the Maran (feathered feet).

So it looks you've got two unknowns, and you ordered 1 "Americana" (Easter Egger.)
Probably both unknowns are Easter Eggers, and they are probably both pullets unless the hatchery made a mistake in the sexing.

From the hatchery's FAQ page:
https://www.mthealthy.com/faq
"We send a 2% margin of extras in every order. This is in the case that something we’re to happen in the shipping of the birds. The extra birds sent will always be something off your order.

Example: if you order all pullets, your extra will be a pullet. If you ordered broilers you’ll receive extra broiler(s)."

We read that and we were really happy that it was definitely a pullet.
