I had some latches on my coop that were not raccoons safe and one got in and grabbed one of my young hens. i changed the latches and thought that my hens were safe even though the raccoons came back several times , despite having some pretty large rocks thrown at it, but just last night the raccoon got another hen while they were out in the yard in broad daylight! (about 7:00 at night when it still very bright outside this time of year). what should i do to prevent the raccoon from returning? i'm not sure that trapping it and killing it would solve the problem since there are certainly more than one in the area. i am also considering electric fencing, but also unsure since i live in a residential neighborhood.
