Your little hen is so cute! She reminds me of one of my dark Norwegian Jaerhons. I don't have a picture of her, but I do have a pic of a roo with similar coloring that I sold to a BYCer in North Carolina. Maybe it will help? The Jaers are a small standard size bird ...What color is your hen's legs?
Totally not sure! She is such a pretty buff yellow color with this great black and white tail... I need to look at her a bit more tomorrow in the light... I didnt get to hold her until dusk.
