That IS bumblefoot on both feet. Continue to soak daily and apply Vetricyn or plain neosporin on both feet. If little improvement in a few days, then you will need to surgically remove the bumble. There are many YouTube videos on how to do that.
Best wishes and Be well!
We have bumblefoot experience, Al have done full surgery on another chicken previously. this seems very different. But we are treating as bumblefoot. Nightly soaks and banax spray internal iirigation , neosporin and wraps. She has no hard lumps like the core normally feels. Time will tell.
