I just don't know the best way to deal with this. My bantys are in a shed which we insulated the walls and ceiling on. The floor is off the ground and during the winter would alternately freeze and thaw. I cleaned several times to make sure nothing was building up and since the weather broke a bit last month I am cleaning it about every 1-2 weeks. When I cleaned it out last week I noticed two of my silkies 'thumping' around. I picked one of the girls up and a couple of her toes are literally encased in what looks like and is as hard as concrete. Because it was cold, I kind of assumed it was frozen food. I sat with one of the girls and soaked her toes in warm water and tried to scrap off some of the hard mess with little success. Any suggestions on how I can get this off their toes? Should I just keep soaking and scraping or is there a better way.
