I would toss compost on top of everything.
Some people write about starting their compost with branches on the bottom... you have that already.
The foxes? They're more afraid of you than you are of them.
As a general rule of thumb... if you don't get between them and an exit... they will usually go for the exit.
There was some frenzy in the news recently about a fox biting people... I think it had rabies or something...
https://www.npr.org/2022/04/05...
Made the news because it was so unusual...
I really wouldn't expect an issue with this compost pile....
I think I would probably avoid adding things to the compost that might attract the fox...
Or?
Having the fox clean up the meat scraps might appeal to some people... And... when the wild animals remove the egg shells from the pile... Isn't the end of the world... God uses many different organisms in the production of compost...
