I'm new to the world of chickens and have five 2-3 week old pullets indoors right now. I am getting ready to set up their outdoor coop and am looking for advice on how to "predator proof" the coop. I have a premade coop. How far down do I bury wire around the edge? I've read about using hardwire wire, not chicken wire...what's the difference? Looking for any advice I can get!!
