For the past year I was pretty sure we had all hens, but now I'm confused. I ordered all female chicks from a hatchery and they all grew up fine, I was convinced they were all pullets as they got older. Now I have one RIR that has been harassing my other hens, and it is JUST like a rooster mating with a hen, but this is the most wimpy "rooster" I've ever seen. The tail is maybe a touch darker, but not much, not longer at all, the chicken is a little bigger. They just got done molting so he/she is hard to compare to everyone with their feathers still coming in the rest of the way. I'll get some pictures a little later, I can't get out to the coop at the moment. They're 1 1/2 yr old now, what rooster characteristics would it have? I'd separate it from the flock and see if it lays but not everyone is laying after the molt so that could be one of the hens not laying. Compared to the other RIRs the comb is larger and more red too.
