I need help sexing these chickens!

4 Weeks old barnyard mix. If you can give me the breed, that’s the best.

The following photos are in pairs

The first two are looking like males to me, and the third could be as well. The last two are looking like females. But it is too early to be sure.

I think they are all Easter egger, olive egger and Legbar mixes, maybe with Leghorn or white Rock thrown in.

The first looks like a Wyandotte mix cockerel to me, the barred ones like Barred Rocks/Barred Rock mixes
