I have 3 larger RIR’s one I know is for sure a cockerel his tail feathers are far bigger and so are his saddles. I have 2 like this and their tails look like hens and they’re also not trying to crow like my male. And my male’s tail feathers are more pointed towards the end. These two have more fanned out tail feathers. I’m really hoping these other 2 are females they look like this picture here with the grass background (off the internet) My son was holding her so her til feathers got a bit smooshed.
