What breed do I have?

[Poultrybonkers]

Not buff Orps - they have yellow skin.

They are likely mixed breeds.

Could be buff rocks?

Could be buff rocks?

Absolutely! Considering the people told her they were likely Comets because they had some (which are a specific cross and don't breed true) I'm very inclined to believe they are mixed breeds of some degree though.
