We are a newbie chicken family. We have 3, three week old chicks and are starting to get the coop built. Do you recommend putting in a floor throughout the entire length of the run? I have read different opinions online and now I am totally confused. We are thinking we might build a raised wooded floor then cover with linoleum then cover with sand and then shavings. We live in Southern California and do not get much rain but we do live in the foothills and get predators like coyotes and raccoons, coyotes have never been in our backyard they just look through the fence but the raccoons are regulars. So, we thought the flooring would be an extra barrier for predators plus it wouldn't get muddy since the area where the coop will be in is just dirt ground. Any suggestions and thoughts?
