I am thinking of ideas to winterize my coop. Right now I have a wire floor so everything can fall through. Winter is coming soon and I was wondering what the best way to make it warmer. I had thought of using a tarp to cover the wire and then putting wood chips on top. Another person told me to not use the tarp and just put straw. My only concern with the straw is if the hens will make their own nests instead of using the nesting boxes. What should I do or does someone have a better idea? Thanks
