Newbie here. I'm building a chicken tractor. No hens yet - I want to be ready first. Our predators in northern Alabama include coyotes, foxes, raccoons, possoms, hawks, and owls. Maybe snakes?? I'm covering my run with 1/2" hardware cloth but I'm wondering about the floor of the run. If I cover it with hardware cloth, will the hens be able to "scratch?" That seems to be important to them from what I've read. Plus, I want them to be able to eat the grubs. If I don't cover the floor with hardware cloth but make sure the coop is locked up at night, will that provide enough protection for the hens? If I decide to cover the floor, should I use something larger like 1"X 2" wire or even chicken wire or will that just add a false sense of security. I've been looking at coops and tractors on the internet and some have wire floors and some don't. Also, does any one know if the eggs spoil in the heat of the day if I don't collect them by the time I have to leave for work about 6AM?
