My pair have always freeranged in our backyard, but were making such a poopy mess on top of the chicken coop/run that earlier this week I put them in with our two hens. Wednesday I let them out. I went into the garage to get some food for them, came back, and my female was gone. The drake just walking around aimlessly told me that he didn't have a clue where she was either.
After scoping out the neighbors backyard's the best I could, I decided to head over to the retention pond behind us, as I could hear some ducks quacking. I walked in the house to tell my wife, came back out, and there she was, sitting on top of the coop (not there before). I don't know where she went, but at least she was only gone about 10 minutes.
I haven't clipped wings yet, but may have to do so, as I don't want her to mate with anyone but her partner here at home.
