Your case seems to need immediate aatention. I would soak the animals every day when you get home. You will need to do this until they can get rehydrated. May take a few weeks. Lost toes isnt a big deal, but the strees it will create may be problematic. If they strat loosing weight hen you need to separate the sickly ones from the still healthy ones.
Good luck... hopefully it isnt a bog deal, but you need to get it under control immediately, or they will all die off.
