Hen with a swelling back toe

[Fluff to Feather Farms]

My silver laced Wyandotte hen Ginger, has had a swollen back toe for about a year now, and I’m concerned. I originally thought it was a bee sting, but it definitely is not. Sometimes it fluctuates in size; one day it’s big then the next it’s smaller. Here is a picture if it helps at all.

She also limps. She is lethargic but that could be unrelated. She will sometimes sit down like her foot hurts. Her toe is not discolored. It is sensitive too.

If you have any idea that would be awesome! Thanks in advance.

Have you checked for bumble or a cyst?

I don’t see a bumble, but I don’t know how to check for a cyst. Do you know?

I can’t find anything on google but it is as hard as a rock! Could that be a sign?

Google is useless in the respect.
Can you wash it off so we can see it clearly?
