Chicks Cockerels or pullets?

[ChickyChickyChick]

I have six chicks that are 4 weeks old yesterday and today. They are all lavender orpingtons. I have two of them that are lavender cuckoo orpington which I know are cockerels, sexlink gene hen was cuckoo rooster was solid lavender, I think there might be another cocker of solid color but I'm not sure. The one to the left in the photo and the second one off the right are my confirmed cockerels.

I see 3 roos. Two on the left, & one near the right in between the other two chicks.

If their comb is red at 4 weeks they are cockerels. Females won't have a red comb until ready to lay eggs at around 4 to 5 months old.
