Hi, first time on here and sure similar info but can't find a clear answer. Issue: Lost 3 birds. One Leghorn female and 2 Guineas. One each of 3 nights in the exact same location in the run. Only 1 bird each night and all others in the coop. This am looked closely at Guinea and head was gone legs stripped of meat and leg bone broken. Did not see "teeth" marks like if my dog chewed a stick though. Coop run info: About 15ft X 25 ft. 8ft tall. Hardware cloth all around and out 2 ft on ground. Top covered with aviation net. Inside the coop construction sand. I can find not a single hole or open issue. Net is still stapled and zip tied in place. No holes in sand that animal dug under and through. No holes in hardware cloth. I have 2 roosters. And though spunky can't see them doing this but not sure if birds eat each other. Full water and 30 lbs food. Total of 12 Guineas and 6 chickens all together since day olds and now about 5 months old. They free range in day and go in run/coop at night. Any ideas? Would one of the roosters kill and eat like this at night? If a predator then wouldn't it try to get other birds vs just 1? No feathers, parts, etc. nothing outside of run. All deaths same corner but smooth sand, no holes in wire, net at top intact 1x1 holes all fine, no hair or feathers or blood etc. I'm stumped and not sure what to do. Love input and I can send pics of coop but I and wife have looked and no holes.
