The ducklings are five now. One of the Pekins, the biggest one is missing. I was gone 6 hours, and now one is gone. They seem to be fearful of the water now, they were waiting for me up by the garage. They could have gone inside but they didn't. There are no signs of what happened, I've looked all over though a body would be hard to find in the raspberry bushes. I figure a hawk or a snapping turtle. The turtle would explain why they are staying away from the water.
