So a picture is the best way to describe what is going on. Seems like it's getting worse over time. The closest 8 week old chick there is a blue fauvacauna. As a baby her neck was fine, but about month ago, I started noticing her left breast looked larger, and as I palpated her, it was the neck part of the spine. Everyone else is fine, and she eats and drinks relatively normal. She runs around, but almost in an arc as she doesn't run straight forward, and her head is almost always now pointing left. I'm wondering if she should be culled, or if I should just see what happens.
