Did she have a legband when she arrived? Meyer appears to put colored bands on some of the rarer breed chicks, and list the color of the band on the breed page. If she had a band, and if you remember the color, it could help figure this out.
Looking through their "rare breeds" section, I see Swedish Flower Hens and Olive Eggers as possibilities. The olive eggers are hybrids of various sorts.
I also find "Lakeshore Eggers" in the section of colorful layers--they are hybrids of Cream Legbars and other breeds.
I think Swedish Flower Hen looks most likely.
When she starts laying eggs, that could help figure out what she is.
