I noticed that one of my Saxony ducks has a lump on their bill. Some online sleuthing reveals others that have had slightly similar issues, but a bit different. This bump is hard and has no discoloration. I checked inside of the mouth and noted nothing abnormal. Here's a blurrier picture but you can see the lump a bit better. Anything to be super concerned about? Something to keep an eye on and see if it goes away/changes?
