I agree with Lindsey that the white chest indicates some pied in there also, Recessive Pied seems likely. I don't see anything to make me think TCB, the markings on the wings seems strongly black all the way down even though there are less of them due to the Spangle.
I have also noticed the white crop area, but thought maybe it was the lighting making the sky blue colour paler than it really is. And it's clear that she has developed irises on her eyes, I thought full recessive pieds keep the baby black eyes.
Maybe she's a combination pied or an oddly marked dominant pied.

You are missed and never will be forgotten.
