Bumble foot or something else?

[u/Bunnykoofficial]

Noticed this lump between one of my chicken’s toes. Checked for a lodged stone but it was clean and couldn’t find the classic “dot” that is associated with bumble foot. Lump feels hard and she hasn’t been limping at all except maybe not putting full weight on that foot when standing. What is it? Do I leave it alone or treat it? No vets where I am
