This is the first time I have ever lost one of my birds in all the years I have been raising birds. So I walked to the coop to let the birds out in to their run (with no top) and there was feathers all over and a dead guinea a few feet away not near the edge of the run. She was all ripped up so I think it wasn't a raccoon. I know my predators and how they kill chickens in their own way but I'm thinking this was an owl. There is no feather tracks and looks like it actually ate some of the guinea. I think it's weird though because I have a rooster that came from no were and he decided to call this home and one of my hens that sleep on the fence. But that fence is about 12 feet away from the coop. And quail in a coop on the ground and bantums in their hutch right under were the rooster sleeps at night. Why didn't the get killed to? I'm happy they didn't though. Thanks for any suggestions.
