I wonder if we have some neighborhood pranksters.  Julie found my outside water faucet turned on with water gushing out.  Then it happened to hers.  Then the chicken coop clean-out door propped open and the carabiners taken.  Let's keep a careful watch, and maybe I'll rig up a motion-detector light on the coop.  I think I have a spare in the basement.  And we have to get another carabiner with a twist lock on it.  Darn it!
