I have a 5 month old RIR. Yesterday and this morning I heard 2 crowing sounds that I think came from her/ him? Now I am really worried that she is a he. We can't have roos where I live and she is my little girls favorite one. Pictures are no help- the chicken looks like some pics of hens and some pics of roos. It does have some deep green tail feathers, but not a lot and not very long. It hasn't started laying though. But this seems really late to be figuring out that it's a rooster. DH says it's the most effeminate looking roo he's ever seen, if it is one. I have some silkie bantys that are about 2 1/2 months old that I am not sure of the gender, so there could be roos in there, but this sound was much deeper and bigger than I think they could make. Totally confused!
