Runny Noses in Rabbits

I have noticed that many of my rabbits have moisture on their noses. I have one rabbit who we think may be allergic to hay, either that or it has snuffles. She has sneezing fits a lot. We think it could be from dust or because the water bottle she used to have leaked.

Now, I've noticed moisture on almost all of my rabbit's noses, it doesn't really seem white or thick though and they don't have any signs of wiping their nose on their paws. It's more clear. Could it be Snuffles?
