So the run is complete and I am almost done securing the hardware cloth. I dug a trench around the perimeter of the run but it varies from 4 inches to 8 inches in depth due to roots, rocks etc. I plan on mixing some quickcrete and pouring it into the trench and onto the cloth. Should this be secure enough. If needed I have a ton of cobblestone which I can place around the outside edge of the run. All advice is appreciated.
