I live in Baton Rouge, Louisiana and my family and I are planning to keep some chickens in our back yard. We can have 3 hens and are in the process of building a suitable coop and enclosure for the hens in our large back yard. What should we consider to keep our chickens safe? Though we live in the middle of Baton Rouge, we do have owls, hawks, snakes, raccoons, coyotes, foxes and at least 1 bobcat. Any guidance you can give us would be most appreciated!
