I’ve always wondered if she was someone kind of dun, but I wasn’t sure because my other dun birds were always more grey. Here are her parents.Dilute blue... commonly referred to as dun. Probably has a little bit of bronzing which gives it that sulfur look when dilute is in the equation. Is the parent an actual black? or is it a dark check t-pattern bird? I think I see what is a tail bar, and that along with the bronzing makes me think that the parent is a t-pattern and not an actual spread blue (black).
