That was my initial reaction, too - an Isbar - but splash. I agree regarding the build, as well.She doesn't fit any of those either...unless there's something with the blue isbar. Not real familiar with those so let me look......
As a splash bird, she could be one of these (note the splash chick at the bottom). The build looks pretty close.

Egg color....both Glynda and Lady F got some of both eggs, right? Do you have pics of all the eggs before they were placed?
Wow, @BY Bob -you may not have gotten what you ordered, but you may yet have a blue egg layer! She is a cutie (both are), and, regardless, I know she will be loved by you and hopefully - since raised as part of the flock, BOTH (hint, hint, Queen Aurora) will be accepted as FULL chickens by the flock.
