Hens or Roos? (And bonus points for breed 😃)

[Pamdsa]

Is anyone in the mood for a game of hens or roos? These are school hatching program chicks - about 4.5 - 5 weeks old. There’s one very obvious roo, and 1 (I believe) obvious girl - but 4 I’m undecided. Thoughts?

I think I see austrolop and Rhode island red then the white one with brown on his wings look like a sex link roo, not sure of the white one's
If you could post better close up pics of them individually it'd help

Most school hatching eggs come from mixed flocks. Whites appear to be mixed breeds. They have white skin. Black could be an Australorp. Red could be a Production/RIR.

We need to see combs on the far right two that are facing away to sex them. From this side they lack male specific coloration like their obvious brother, though.

The chick with the red over the wing bows is the only clear male.
