Unsolved mystery

A few days ago my dad and I noticed that his much loved flower-box in the back porch had been ratted. Initially he was convinced that some scallawag had jumped our 6 ft gate and stolen his pansies but closer inspection showed the flowers where still in place, just a little worse for ware. A rat was supposed the culprit and we went on with our day.

The following morning my dad got up for work before the birds to find the flower box tampered with once more. Frustrated, he rolled up his sleeves to put things right once again. As he parted the soil to replant the upturned flowers he caught sight of something buried about 2 inches down. Closer inspection and a slimy touch confirmed that it was some sort of ... flesh. Shocked but entranced he dug the item out completely and soon discovered that a whole oven-ready chicken had been buried under his pansies. I'm utterly bereft at not being present at the moment its discovery. Almost as strange was that all the pond water had gone too, along with our last few surviving fish.

He stumbled into the house and declared that he'd "found some meat in the flower-bed" at the top of his lungs. My mother and I sprang out of our beds like the house was alight and pretty soon were online researching voodoo hexes etc. 

So, we still have no idea how the chicken got there. It could be a fox but there was absolutely no way it could have made it into our brick walled garden, especially with such a large chicken in its jaws, (and there's no way it got up on its hind legs and burried the chickden so dealicately without leaving a tooth mark, unless it was some sort of mutant fox empowered by drinking all our pond water.) 

Any theories? Or any knowledge of poultry curses?

Talk about an ambiguous omen for the new year! I feel like I'm in a David Lynch movie.
