I had about 14 hens, and now I am down to 3 and one rooster. The predator had been sneaking in to the coop at night, and took a about 10 hens and one rooster right out of it. We tried waiting outside the chicken coop for it (after we realized what was going on) but it never once showed itself. BUT the first time I forgot to lock the chicken door on the chicken coop, I lost a chicken before 9PM. We then tracked the feathers out to a hole in the back pasture (where the sheep are) smoke bombed it, and covered it in with dirt/sticks and it has remained undisturbed. And I thought that was it... But I set a live trap outside the chicken coop, just to see what would happen and caught a cat. I don't think this was the culprit, since whole chickens just disappeared. So, I put the live trap inside the chicken door of the chicken coop-- basically so that if the predator tries to get in the door, it jumps in the trap and sets it off. Been doing this for a a couple weeks, have not caught anything. Just when I thought my chickens were safe. My very last silver laced wyandotte disappeared. And, I KNOW it was there when I left for work at 7:30 because that's when I let the chickens out. I was thinking she might have wandered off to try and hatch some eggs (she was going broody and I kept taking her eggs away from her in the coop) and got eaten...but still, it's very weird that she disappeared during the day. So, do you think this is a fox? And if so, what is the best way to trap/kill it? My dog is completely useless, he's an American bulldog and he is pretty good at herding and excellent at 'catching' sheep (what he is bred to do) but there is no way he would stay on the farm if we let him outside during the day. If I put him outside at night he would sit by the door and bark until I let him in.. I'm pretty much at my wits' end and the only thing I can think of to do is fence the chickens it and not allow them to free range anymore.
