Hello everyone. One of my budgies has developed a strange deformity on her cere right inside/next to her nostril. As you can see in the following pictures one of her nostrils is completely blocked by this growth. It doesnt seem fluid filled, instead it feels hard like tissue. The other nostril has also narrowed too. Also her cere skin covers the upper part of her beak. Cere and beak are a bit shiny in pics because i put some fungal cream on them.

Waiting for your inputs. Please tell me if you have ever encountered something like this and what it may indicate?
