Can anyone tell me what breed these two are? Or are they just a mix

Looks like the roo is a silver paced wyandotte, don't know about the other one. I can't really see it

Probably a mix of some sort.
Are they bantam sized, or larger?
I don't know much about chickens that hold themselves that much upright. Maybe Serama? (A very tiny breed.) Or some kind of Game Fowl? (Not all Game Fowl are kept for fighting each other-- some are just raised as pretty pets or for poultry shows.)

They look like SL Sebright mixes. The pullet might be mixed with OEGB.
