I'm about to start building a raised deck for a shed at the end of the garden and would like to build a fox den in the earth underneath it.
My thinking so far is: -
A rectangular deck six feet by ten feet will be supported by six posts set into the ground and the den excavated in the middle before being capped by paving slabs and covered with earth. A piece of drainage pipe will lead from the den to an entry/exit point set at the side or behind the shed.
Any suggestions on a minimum size for the den, especially the height/clearance, and the diameter of the entrance/exit pipe?
