Eleanor Broke a Nail

Yeah, you laugh, but when Scott went outside yesterday morning to let the chickens out, there was blood on their roost, and not just a little blood. Scared us to death. The chickens all looked OK and it was not until we noticed blood on Eleanor’s claw that we had any idea who was injured. Unfortunately, a chicken’s claws are used primarily for scratching around the dirt and muck. How are we going to keep this from just filling up with grime? Has anybody out there had experience with this sort of thing?
