Magpies feeding hedgehog!

I seem to have developed a very convoluted way to feed hedgehogs. I put out suet pellets in the morning. The magpies arrive and stuff themselves and then start shoving the excess into holes in the lawn and flower beds. Overnight little excavations appear in the lawn, accompanied by lots of black scat. I put out some suet before I went to bed last night and it is now gone so guessing it must be a hedgehog stealing the magpies' stashes.
