We have a chain link fenced in yard for my niece and nephew to play in, and its where we are putting our chicken coop. It has 2 doors that I try to make sure get closed every night. I am putting chicken wire around the bottom of the coop, stapled to boards that run along the ground. Do you guys think that will be secure enough against any predators, along with being inside the chain link fence? or should I bury the chicken wire too?
