I have a pekin duck (5 weeks old) that was missing this morning. No signs of struggle no feathers and the other 5 were still out there. Of course i was sad and was going to get some more this afternoon. I put the other 5 in the pen just in case something wanted them. i just walked outside to find the pekin (whose name is now houdini) not only outside but in the pen with the others. I know im not crazy. lol
