We have never had a stray get in the yard. We will put better wire, we needed to get them out there and didnt have the money for better wire. Havemt seen a racoon in my neighborhood but possums yes. Do you suggest an actual door we can shut on the coop?
We never knew we had city Raccoons or city Possums til we got chickens.
Yes, an actual locking door is recommended on the coop AND the run because chickens will sleep/roost right through a predator attack and stray or feral cats will enter your coop at night to get at the chickens if you have an open door. A sturdy top on the run is recommended against aerial predators. We never knew we had city Chicken Hawks or Red-tailed hawks til we got chickens!
Crows are in our area but they don't bother adult chickens. In fact, crows seems to keep other aerial predators away when the crows flock in around the neighborhood. But crows WILL go after ducklings or chicks so don't recommend keeping babies out.
