I have bantam buff orpingtons, and although she looks very similar, mine do not have the black tailfeathers or the black lacing around the neck. She is pretty though. Hope she settles down for you.
If she is clean legged Ideal has buff columbian wyandotte bantams. I don't know much about wyandottes but they are a real favourite show bird and a very pretty small chicken. Could she maybe be one of those?
She's clean legged and the comb is basically non-exsistant....but is a single type. The lady said she was a spring chicken... so she could be 4-6 months old or so. If that helps any She has really yellow legs, you can see one of her toes in the pic.
Is there a site that shows all the different banty types?? I know about feathersite, but is there anything else?
Sorry I edited my last post when you responded that one time... I'm a slow typer...
