Roo or Hen?

Hi! We’re first time chicken owners and had gotten three chicks from a straight run batch. We think two may be roosters and the other a hen. They’re hitting their 6 week mark and we’re worried about how the hen will if she’s by herself in the coop. We can’t keep roosters where I’m at but they’ll be relocated to a friend’s farm that is in need of roosters.

Are the roosters? 😭
