That's a lot of birds to lose! We have them in the area also but so far have only shot 1 right on the edge of our yard. We have 4 fox in the immediate area too. I'm assuming it's a coon but I could be wrong. There's been a trail of feathers each time and that's it, no blood or anything.Hopefully you catch him. I haven't had troubles with coons. One year a coyote took 10 birds before we got him. I know the feeling of losing them.
