When we worked it out, we were using torn cardboard as the 'brown' layer in the compost bins and some of the boxes had held dried cat food.  It was the pieces of those - and they weren't very big bits - that were being dug out and discarded in frustration by a fox!  the smell and the reality just weren't matching up   )

Foxes are the same with dried chicken poo here - it then becomes as question of their IQ and how long it takes them to learn that it tastes very much like cr@p and leave it alone (although when it comes to BFB I find their IQ never rises to the challenge.  )
