It could be a form of dry shell rot. It is contagious and can be caused by fungus or bacteria. I would take them to a vet and get them looked at, you may have to get a perscrition for a cream and as well as directions for cleaning the area daily and perhaps a special soaking solution. You need to know what is causing the holes and do a thorough cleaning of their enclosure to get rid of what ever it is (ie bacteria or fungus) as well.
