I have a barred rock that I noticed has some redness between the toes, and on one foot she has some swelling at joints. I looked at bottom of feet for bumble foot, and I don't see anything like that. Maybe leg mites????? I'm new to chickens so I'm not sure what it is and what to do. here is a picture of the swollen joints. the redness doesn't show up as much in the pictures, but you can see some of it. I don't see any leg mites, but I have an untrained eye Here I just circled the swollen spots.
