Serama chick sexing

[Lol123]

Hey all, hatched these two seramas just over a month ago. Can they be sexed this young? Was thinking black is a cock and other is a hen. What do you guys think

The black one is a cockerel. Keep an eye on the white one (or update in a week or two), it might be a cockerel too

Still not much development on comb and very light in color
