what breed are these 3 week old chicks?

Oh wow that’s really interesting. Usually they have the same amount of toes on each foot. Maybe it has some five toed breed somewhere along the line? Silkie or faverolles maybe?

i think it is a deformation and the people i got them form think the 5 toed ones are dorking cross.
