I have been having a mother racoon and 3 babies hanging arround. They go into my barn and eat the cat food, and get into the garbage when they can. So far they haven't gone near the chickens. I don't have a safe coop built yet, they have a 3 sided leanto that they go in at night, and a covered 12x16 chain link dog kennel as an attached run area. If I put a 3 wire electric fence arround the chicken area will it keep the coons out till I can get rid of them.
