The good news is that the skunk is out of his misery. The bad news is that we won't be out of ours for awhile.
Yes, skunks do spray when you shoot them. (Good thing Madman is a swift runner.) (Doubly good thing that he got that knee repaired last year so he could be a swift runner again.)
So the chickens are safe again for the time being. Until the next predator moves into the neighborhood, anyway.
Though the skunk smell might hold them off for a bit...
