10 week old Roo? Hen?

[Chicken_foreman]

The chicky in question is a black tailed red french maran from cackle. (First 3 pictures). Hatch date was 3/17 for all of these examples. Second picture is my cuckoo maran rooster same age, and third picture is a hen same sex and age for comparison.

I am suspicious of chicken #1 because shes been aggressive with my 5 week old babies and her comb is getting more red than her sister.

Looks like a pullet to me.

At 10 weeks that's a pullet. A cockerel would have a much brighter comb.
