Pictures would help a lot. A month old it's still pretty hard to tell the sex on a lot of breeds.

At about 8 weeks the faces and combs of the males will begin to turn pinkish. pullets combs will be smaller and will remain yellowish until just before they start to lay.........Pop

knowing the breed would be nice

RHR pullets will have a black stripe on their head. Our RHR chicks are 4 weeks old, and I can alreadt tell the roosters from the hens. The male's already have much larger combs thant the females. When they're younger, tou can tell by the wing feathers. On our Japanese bantams, the males have pointy feathers, and the females are rounded. I found a post here yesterday that had a you tube link which shows you how to feather sex.
