Sounds like a parasitical growth of some sort--cycst. Perhaps all of the Rams came from one location (breeder) that has an infection, or a wholesaler, or dealer. The other alternative is the water source and what's in the water. My first bet is that they're already 'infected'. But since I'm at work, I don't have any references regarding the conditions you mentioned.
