Quote: Thank you! You're the first person I've know that has one!
How cold can it be outside and still be able to use them?
I used them all last winter. So -20 degrees. I have a small area I insulated for the winter so I could brood chicks for early spring hatches.
Quote: Dirt is good if you have good drainage. You will have rotting issues and predator issues with dirt floors. Any chance you can cement and dirt over the cement? I have wood floors, but my coop is up off the ground and hard wired to keep out predators. I chose to remove ducks from the chickens because of the water issues. Ducks need more water than chickens do. They also keep water containers dirty. I do not feed or water in my coops to keep out moisture and mice. Mice are attracted to the feed. (that you bought and paid for)Lice and mites are carried by mice and so are a host of other nasties. Easiest way to keep a coop pest free is to remove a large source like free feed. Best way to keep combs from frost bite is to keep the coop dry. Best way to do that is remove the water and make sure you have good air flow.
