Hen or rooster?

[Slw]

Hens or roosters. I have 5 Ayem Cemani chicks they are 5 weeks old from the same clutch. I have 2 photos of 2 of them. I’m not good at feather or vent sexing. The combs are solid black. I only know that the other 3 I have are roosters because they are constantly sparring, even against the 7 week old Easter eggers

All chicks will face off with each other as a way to display dominance, so not an indicator of gender there. I'd give these guys a few more weeks but if I'd have to guess, first is a cockerel. Second could go either way at this age. Black skin breeders are a bit tricker to tell until they are older.

Thank you
