Hi, I’m extending my chicken yard. I’m wanting to make it about 7ft in height, and as long and wide as possible- until I run out of money. My question is, should I cement the posts into the ground, or no cement and just a packed down hole? Or is there another way to stake the posts into the ground? I’ll be using hardwire mesh for the sides and avian netting for the top, if that’s pertinent..
