Weird bump on duck

[animal and duck lover]

First of all, vet treatment is expensive and not an option unfortunately. My duck seems to have a bump on her back under her neck. No idea what it is and as I looked through her feathers I could not see any signs of injury or even where the bump could be coming from

Any chance you could get a picture of it?

Hard to suggest what it might be without a picture. If it's under her neck, near the righter side, it could be the crop. Is the bump there this morning?
