Strange eggs from one of our girls

[MutthaClucker]

We've been seeing some strange eggs from one of our ladies recently. As far as we know she's never had any infectious issues besides dry fowl pox which our whole flock went through several months ago. Any thoughts on what could be causing these strange eggs?
