Possible roos? 4 week old mixed breed chicks.

[Billi1011]

I hatched 4 chicks 4 weeks ago, and though I know it's early still, I was wondering if anyone could tell if any of these are roos by their combs/waddles mainly. I hope we get at least 1. I'm thinking the first one will be a roo based off it's comb color and size of comb/waddles.

Chick 2

Chick 3

I believe you are right, but you never know for sure until they crow

Looks like you have 4 cockerels.
