I'd let our girls fend for themselves, and not feel bad for the wasps. But, if you want to drive off the wasps I have a suggestion. Now, I have no idea if this is safe so let a bunch of other BYC'ers weigh in before making your decision.
I spent 10 years as a mailman. We routinely find wasp / hornet nests in mailboxes. we would sew a couple of mothballs into a little cloth pouch and toss it in the afflicted mailbox. It never failed, ever.
You might be able to staple a pouch or two in strategic places in your coop.
I have no idea if it's safe. Please get other opinions on this first, before trying it.
