I know quite a lot about foxes, living in a remote area.
The farmers which used to keep sheep were always troubled by them, the farming community employed a gamekeeper who used every trick in the book to eradicate them.

Foxes are not nice animals, they are one of the few wild animals who kill and mutilate their victims for fun.
When they break into a poultry coupe, they will kill everything in it perhaps carrying away only one carcase.

I remember as a child going into our henhouse to be met with what looked like as scene from a horror movie decapitated carcases litters the floor legs ripped off, heads scattered everywhere and not one body had been removed.

Shed no tears for Mr Fox.......remember the "sly bold Reynardine."
