pullet or roo?

[first_chicken]

I got 2 easter eggers, whose father is a splashed Ameraucana and mother is either a saphire gem or other breed. The first chick grew really fast and in just 1 month, showed a red comb and even started to crow. So I rehomed that definite cockerel. By comparison, I think the other chick is surely a pullet. However, now it is 9 weeks old, and the remaining one looks like in the picture. The tail feather seems like a roo, and is the red comb a sign of roo at this age? Thank you.

I'd say cockerel. That's pretty red for the age.

I would say rooster because the tail shape and how red it’s comb is

Thank you! I just don't understand why the other roo grows much faster than this one

Do all kids from the same parents mature at the same rate?
