Are these Roos

[S_hall89]

I hatched a set of 5 cochin bantam eggs on 8/16. I have a lavender that I can already tell is a roo and he was born after these two. But these look like hens bc they have no color to their combs still and no growth to the comb. Their wattles however are very noticeable. Can these two be hens even if the wattles are showing pink/red? I have attached a picture of the lavender just for reference.

Were these all from the same parents? Looks like you have the one roo and the rest are hens but since they're 4 wks, waiting another week or so to be sure is a good idea.

I would say the white one is male. The others I'm not so sure on. For now I think female.
