Hi, all. I had my first losses to predators yesterday, and I'm wondering if you might be able to help me figure out what did it. Here's the scenario, and a description of the damage to the casualties. (Sensitive readers be forewarned.) We were free ranging 16 Buff Orpingtons (15 ladies and a roo) and 5 Rouen ducklings (4 drake and a hen), all about 10 weeks old. We live in the country in northern PA. Between 8:00 yesterday morning and about 1:00pm, something came down through the field above the house and attacked. It left 3 bodies (the roo, a hen, and a drake) and 3 have gone missing (the female duck, a drake, and a hen). My BF said the 3 bodies he found had puncture wounds on the neck, and that the necks were crushed. He found the drake in our back yard, and the roo was caught up in the newly installed garden fence up the hill. The surviving ladies were all clustered together on the far side of the garden outside the fence, and the two surviving ducks were right by the back doorstep. He was able to follow the trail up through the field and hill behind our house, but lost it when it got on the landlord's big lawn. We're thinking either foxes or dogs. We chased off a pair of dogs last Saturday afternoon and had no casualties, so maybe they made a return visit. I read that foxes, weasels, minks, fishers, and dogs kill for sport, but I feel like if those two dogs returned and had all afternoon to work, they would have decimated the entire flock. There is a lot of water on our hill, two lakes on the property, so minks, weasels, fishers, and the like abound. There are definitely coyote up here, and we've seen signs of a big cat, too, but the damage doesn't seem to fit these animals' MOs, does it? What do you all think killed my birds? And will building an enclosure help to protect them?
