Serama sexing?

[Jessx]

I have a 4 week old Serama that I am wondering if anyone can tell if it’s a roo or hen, the breeder mentioned all her breeding hens have very large red combs for the breed too to make it even more difficult

males have red combs very early and many crow within a couple of weeks. that's my experience

It's a cockerel. It would be extremely unusual for a pullet to have a comb that large and colorful at 4 weeks. That goes for any breed.
