Need help telling the breed of these 2 chick please

[JonathanL23]

We go 2 chicks this past winter from a family that hatched them out as a experiment, but they lived in the city so couldn't keep them. So we took them in but we have no idea what breed they are 4-5 months old, not very big. I'm not really familiar with the small breeds, also if you can tell if they are roosters or hens let me know. i think the black one is a rooster and the little grey one is a hen.

If they are 4-5 months old then they are both pullets. Most likely Ameraucana crosses.
