I just noticed one of my hens has a problem with both of her feet. It's between the toes, in the webbed part. On the outer webbed area she has a fairly good sized lump, on the one foot it's bluish in the center, on the other foot it's just the bulge. The inner web are on both feet don't have a bulg yet but do look a tad swollen. I'm not able to get a hold of her right now to see if there's a problem on the underside-rooster wont let me near her. I looked in my book but i couldn't find anything except Bumblefoot and this didn't fit the description exactly. Got any ideas?
