Gender of (I think) leghorns and black australorps: 4 weeks

[Heathermbm]

Hello! I’m trying to determine if I have hens or roosters, this is our first flock so I’m not sure what to look for. They are all about 4 weeks old, can you tell at this age or do I need to wait longer? Thanks! (Also can anyone confirm that the white ones are leghorns?)

Looks like two cockerels and two pullets just based on the combs! Still early, but looks like a 50/50 split at this point!

That is what I was thinking too, going off other posts on here. We decided we would keep one rooster to help protect them hens so I guess I get to pick one soon.
