What breed is this?

Got this chick from a local hatchery, sold as a bluebell egger. She seemed fairly normal as a day old chick (we thought she was an ameracauna), but as she's gotten older shes looked stranger and stranger. The first photo is her at a day old, the next two are a week or so, then the last three are today at about 3 weeks. Googling so far has been fairly unhelpful and she definitely doesn't look like our other ameracauna.
