Alone at Christmas.

So...we were a little apprehensive leaving the 'chooks' to fend for themselves while we were away for Christmas. We returned to find only one casualty....Dou-Mu now has only two chicks left from the original eight.Yesterday after the cheese maker had gone I was awoken by a loud commotion and rushed out to find a large Swamp Harrier on a low branch above the alarmed hens. It flew away at the sight of me and did not return.A chance encounter or a return visit?
