Hi, great to see more people with elongated! They are one of my favorite species! They are very friendly and social, very gentle! I recently just added a second one. Great choice!
I’m with the others, the beak needs trimming. And very well could have caused injury or etc, from attempting to eat off alignment. It could be a totally different issue, such as maybe an abscess. Either way, the beak needs trimming.
Russian, make sure you soak he looks dry. I would also change out your substrate to something like coco coir, top soil mixture .. or other tort friendly bedding.
