Hopefully, seriousbill will pop in on this one. I'm not 100% sure your pullet is a pullet. She has tail barring and not tail black. I did have one cockerel who looked like that. He was very small, too, but was very much a boy. The stippling down the back will change alota as they molt. I could post pics of my breeder Dels when they were that age, but they are not on this new little laptop.
