She's a spitting image of Brocky (shape, mini feathers, colour, and plenty else) without socks. Definitely a brown! He's part TB, part something else. I like to think Andy. Whatever she is, if she's like him in brains as well as looks she'll be a clever clogs! And have a big opinion of herself LOL.
Nothing wrong with a brown - imagine how muddy she would look in these pictures if she were a grey!
