Serama Gender Check

These 2 are 17 days old. Maybe 3 days ago I noticed some pink/red on the comb of the black and white one while the lighter one has remained the same, anything thing else to check while I wait for the feathers to come in? I hope it is a boy their crows are the cutest!

It does look to be a cockerel. The other is so far looking like a pullet.
