How would I be able to prevent icy walkways when my hens free-range? I don't remember doing anything last year. We usually shovel as it's falling so it doesn't compact and become ice, but this year it's colder and it's icing up plus we have the snow melting off the roof and right onto our doorstep thanks to a broken gutter. I would think they'd eat the salt. We started buying the pet safe variety after getting our first dog 3 years ago, but I would think that even that would be harmful to hens. Untreated kitty litter? Sand? Gravel? Any other ideas? We haven't tried anything yet.
