Today while foraging in the backyard my campbell and one of the runners(6weeks) ate an extremely large green and black spotted slug and now have a lot of slime coming out of their mouths. I have been trying to clean it out with damp paper towels but the stuff is super sticky and doesn't want to come out. Its on the inside of their bills and around their tongues. Will this sticky glue-like snot cause a problem? Will it glue their mouths shut? Will it go away on its own? If not, how do I get rid of it? It is very tenacious.
