My henhouse (which is near our compost pile) REEKS of skunk. Our dog got sprayed 3 days ago, and I sort of assumed the skunky stink was leftovers from that... but it still smells, bad, and I'm concerned the skunk might be living under the henhouse or something... There's no way for it to get into the henhouse, but it could be underneath. I looked with a flashlight, but didn't see anything. what to do?
