We transformed an old dog run into a coop. It's a concrete slab, totally predator proof, 20x12, we have 22 chickens and they free range all day. I live on 2 acres and its fenced. Right now (and for the past 4 months) I haven't put down any bedding, just the concrete. My flock don't seem to mind, and since we live in central FL its rarely cold. I spray out the coop every morning, only under their roosts. Their feeder and nest boxes are also in the coop.
My question is : is bedding necessary? If they're only in there to sleep/lay? If it is necessary, what would be the most cost effective for a coop my size + the amount of chickens we have?
Thank you all in advance for any help you can give me 😊
