5 toes? It's not a silkie, not a favorelle and dorkings have clean legs, probably a mix? Where did you get him? I think you're right that it's likely a cockerel : D
I got him from a breeder who sold me "silkies" and mille fleurs. I ended up getting sizzles, satins, and frizzles (not what I asked for). I also got two mix frizzle/mille fleurs, and then two that looked like the one above. I was thinking cochin mix too...sigh. I don't discriminate against healthy chicks, but man this lady really scammed me lol.
