Growth on Duck's foot

[Wintertheduck1]

Hi all! We have only been raising ducks for a year, and are learning as we are going. Can anyone identity what this is on my khaki campbell/rouen -mix female? We thought it was maybe bumble foot? And can anyone help me re: treatment? Many thanks!

Looks like bumblefoot. There are lots of threads on how to treat it.
