Lump/ Swollen Area on Hens foot?

[lmadeline146]

I have a 1 1/2 year old Barred rock who has never had bumblefoot or any other health problems before. We did have one hen with bumblefoot a few months ago, but nothing since. I noticed one of my hens has a lump or swollen area on her foot. I cleaned her feet after these pictures was taken and there were no scabs, red areas, or other signs of any infection. I never have noticed this before so I don’t know how long its been there. She isnt limping or showing any signs of discomfort.

What could this be?
(Sorry about the muddy feet and run, we’ve had rain and snow recently)

I have a rooster with a toe like this, I assume it broke at some point and when it healed it ended up with a lump.
