4 Rhode Island Red! Roosters or Hens?

[Rhodeislandred4]

I have 4 Rhode Island Red! They are 5 months old. I'm so excited to get my first egg. But still wondering if they are roosters or Hens. I hope everyone can help me to identify them. Thanks!

Are they not crowing? I agree, three roosters..

I didn't heared them crowing yet. But they make noise like when the hen is laying eggs.
