Yes, certainly a fox is capable of such an action, in fact it's normal for a
fox to bury surplus food in good times to use during bad times. On our
previous allotment where there were two families of foxes (and no rabbits!)
we were often digging up duck eggs and once two gammon steaks attached
themselves to my fork much to my horror/surprise. One day I noticed a rat
looking out of the ground at me, it was dead, and had been buried up to it's
neck leaving it's head exposed. Nice! :-)
