I know it's been asked a thousand times before, but each photo is different. I have 4 RIR. I think they may be crossed as there is some dark green luminescence at the tail area. They hatched on 13 July (I got given eggs). All along I've thought they were hens. As they my other roosters were all obviously rooster at a much earlier age. Now that I'm expecting them to start laying, I'm wondering if they are perhaps roosters. Any comments please. I hope the photos are clear enough.
