Weird growth between two toes on both feet - bumblefoot?

[Tyranno-Chicken Rex]

I noticed this weird growth in between my hen’s toes today while holding her. It’s in the same spot on both feet and from what I’ve seen I think it might be bumblefoot but I’m not sure. She doesn’t seem to be in pain when I touch the swollen areas, though. Can anyone confirm if it is bumblefoot/how I should treat it? Also not sure if this is important but she has spurs which I heard can happen to dominant hens.
I haven’t seen this growth on the rest of the flock though so I’m not sure if it is contagious.

I had a hen that had this. The skin on the feet can get impacted with mud, dirt, and manure. She had small spurs too. I just gently rubbed it out each time I caught her. Once the skin is stretched it doesn’t seem to want to heal back. She had this her whole life and lived to be 8. I maintain a flock of about 35 pets and none of the rest have had this. Hope this helps!
