Breed and sex of chicks

[Joshy1718]

These 3 chicks are 5 weeks old. Can anyone help identify breed/color and the sex? Thanks. I’m pretty sure the brown one is a rooster

Brown one is a Cochin cockerel, not sure on colour. The other two are pullets, not certain on breed, maybe blue Marans?

Yes, I agree, the brown one is a cockerel and the others are pullets. Not sure on breeds though, sorry.
