Can you tell me what breed of chicken this is?

[All4Eggz]

Probably!

Because I noticed the black edges of some feathers, which is what cinnamon queens have.
And I've seen Cinnamon Queens being sold at TSC, so this is very likely.

Rhode Island Red = Production Red. The other could be a cross or a Brown or Red Sussex. Good luck...

 

[cmom]

do you think she might be a cinnamon queen?

A Cinnamon Queen is a cross of a Rhode Island Red or a New Hampshire Red male and a Delaware female. The look like Production Reds.
Here is one I hatched out. With her buddies.

Likely a Cinnamon Queen. They're crossed using Silver Laced Wyandottes to my understanding. Definitely not a Sussex or first gen Sussex mix due to yellow skin
