We have a large fenced in area cattle panels outside doubled up with chicken wire. That is the fencing. We are going to criss cross twine over top to deter hawks. The coop will be salt box design. Regular door and window left form remodel project in front of coop. All locking. Chicken door in back hinged and padlocked at night. We have clever coons. Also a smaller higher window in back also left over from house also able to locked from inside. Coop will be off ground but competely made of wood. Coop will be in center of chicken yard. Should we put motion senser light on outside of coop to maybe scare away anything that approches? Or does that even work. We have coons, possumes, coyotes, shunks, stray dogs, cats, hawks and bald eagles in the area. Chicken will be locked up in coop at night.
