New chicken owner here (since May). We are almost done building our coop/run (it took a LOT longer than we intended), but it's rapidly getting cold here in MN. Right now our chicks are in the garage at night & in a temporary run during the day unless we're home & then they do some free ranging sometimes. I don't know if we'll be able to bury the hardware cloth before the ground freezes though. Is it safe to assume that frozen ground will also deter digging predators? I'm only worried about digging, the top & sides of the coop are/should be fine. Any ideas???
