Rooster or Hen?

[Chammer17]

I'm new to the whole backyard chicken thing I have had chickens before but I've always bought them as older not chicks so I never really paid attention to features or how to know whether there a hen or a rooster for sure. Their 4.5 months old. Any help is greatly appreciated. Thanks
