I have 3 hens in my backyard, which has a 6 foot high fence all around. New & sturdy...but something got in and took my hen away. All that was left is feathers all over. The feather trail led underneath my shed (about 6 inches off the ground). The shed is right up against the coop, but still totally inside the fenced backyard. Today, awhile after my hen was killed I get woken up at 6:30 am to frantic hen sounds. When I went out, I see a small opossum in their run area by the shed. Must be living under there. Is that small opossum really capable of taking down a mature rhode island red? Or was it just looking for eggs? We have seen raccoons around & in some areas, coyotes. The neighborhood dogs are always in their yards. What do you think got my hen & dragged it under our shed? I don't want it to happen again!
