I listen carefully at night, from a distance. And if I hear contented sounds or nothing, I go to bed. If I hear squawks? I head right out, gun in hand. Usually it's a squabble over roost space, but last year it was a possum being rude. He got shot.
Picture an old lady, in sneakers and a nightgown, huge gun in one hand, flashlight in the other! I am soooooo glad the neighbors can't see the coops!
