Thank you everyone. It turned out that the one on the rigth did become a rooster and we still have him. He is not aggressive towards people and pretty friendly when you hold him. The other one was a girl but she died suddenly last year. It was a bummer becuase we really wanted to have hens.
Hats to tell,still a little young. However, if I had to guess I'd say they both look like hens. The first one had that tail like a hen. Post more pics later.
The one with the pink band is a little smaller. The lady told me they were about 5 weeks old and the larger one with the purple band must have hatched first. They still look like pullets to me at this point.
