In general, black spots are a harmless variation on some ducks bills. My ducks get into all sorts of scrapes with their bills: my drakes fight and try and bite eachother even when separated by ralis. Some females peck at each other two, perhaps not as aggressively as my drakes. They get scarred bills as a result. Sonetimes their scarred bills flake. All a little unsightly but not harmful.
I hsve never seen or heard of a bill going moldy.
I suspect thst the fuzzyness is keratin overgrowth from scrapes and bangs, but I am not certain. If your duck is healthy and thriving, my advice would be to wait and see if there are any developments
Been watching to see if anyone had any ideas as I didn't know what is going on with the "fuzzy" areas. I agree a zoomed out photo might be useful.I agree a zoomed out picture would be helpful. I have a lot of ducks and some have spots and some don’t. Sometimes they get dark spots from eating a lot of kale or other things like kale perhaps spinach . Turns out it’s not usually a problem. A lot of my ducks are varying amounts of it and have lived many years with it and has no problem. @ruthhope
