Unexpected visitors?

Went to fill hay nets for the horses this morning and stumbled upon some unfamiliar faces. Unfamiliar CUTE faces! These precious kittens wound up in our hay stack. We have no idea where they came from, but first things first: they'll be visiting a vet shortly to make sure they're healthy and wormed. They're not completely feral, and one of the kittens has actually warmed up to us pretty nicely! The other one however, cowers and hides behind the litterbox. Poor guy/girl must be scared :( What would you name these three kittens?
