I woke up this morning to a site, a pile of feathers in our backyard, with two feet left behind, another chicken freaking out in the rose bush, feathers all over the front yard, the gate open and my two dogs there. I immediately checked them for blood, none on their lips, teeth, nails, fur, now where. No dried blood either. They were both running around the bush with the chicken in it but not like lunging at it or trying to attack. I'm put them both away to access the damage, when I came back the one in the bush was just gone. Like poor, as if it was never there except feathers, I went to feed our other chickens to see how many were gone, three left so two were gone. But I'm not sure who did it, I know it sounds cut and dry but let me say why I'm unsure. We used to have 12 hens in total, over the past month they have disappeared over night WHILE the dogs were locked in crates in the house. We have found a fox den up at our barn-neighbor apparently has been feeding them- and seen a coyote at least 3 times at night. It's really a proper game of clue, who did it? My older girl Misa has never harme our chickens, she has been used to kind of herd them tho but never touch them. Our newest girl Piper-ironically who I just signed up for a dog trianing class which teaches them to leave alone chickens, goats, etc- has tried to chase them before but never killed one even though she could easily have caught one. How do I know who did it? And what do I do if it was my dogs??
