So you may have heard we had some nasty animal dig into our coop. Our solution was to move the coop onto the patio at night and weight it down. (It's just a light little chicken tractor type thing) That is working fine and everyone seems happy. But today we were so busy and such that we never moved it back onto grass. Fed them and all of course, just didn't give them the grass time. Is that going to be ok occasionally? Or even for a weekend if we travel? Does it hurt their little feet to walk on the patio all day? I know they prefer the grass because they can dig it up and eat it and hunt bugs and such.
