Ed solved the mystery. Uno wasn't stolen. An owl or hawk got her (most likely an owl). He went to put the ducks to bed and found Bebe without her head Then when he was trying to find signs of paw marks or where a predator could have gotten in, He found Uno's headless body on a path we checked several times yesterday. Apparently it fell out of a tree. So now I only have 4 ducks. I had a customer lined up to buy eggs and everything! No more free ranging all day and playing in the pond. Now I have to keep them penned. I can expand their range by enclosing my herb garden, but this just SUCKS!!!!!!!!!!
