Late bloomer? Help appreciated sexing 5-week Chick

[FarmerSeth]

Hello! I got these hybrid/EE chicks about 5 weeks ago. There were six, but three were clearly cockerels after 3 weeks. I thought I had three hens and 3 roosters, but now I’m suspicious I have a late bloomer!

What do you think? Any thoughts appreciated; thanks!

At 5 weeks I believe it's a male.

Thanks. I was thrown off because his brothers were two weeks ahead of him. I appreciate the expert eyes
