Where did you get her?
I'm thinking she might be some sort of a mix.
Easter Eggers can have almost any appearance, so she could be one. Easter Eggers are supposed to lay blue or green eggs, but most hatcheries advertise that a few will lay eggs in some shade of brown. So an EE that lays cream/brown eggs is one possibility, if we can't figure out anything more likely.
That comb has me puzzled though: it looks to me like a single comb that's all folded up. Cream Legbars have combs a bit like that, although usually with fewer folds. But 7 years ago, Cream Legbars were not particularly common, so it was also rare to find Legbar-mixes (and her color is definitely wrong for a pure Legbar.)
