Well this is a new one for me. I have something showing up every day between 4:00 p.m. and 5:00 p.m. and harassing my chickens. Yet I've never seen it. Today it took chicken #2, and the odd thing is that there aren't even any feathers left at the scene of the crime. I've had previous experience with hawks, foxes, raccoons, skunks and coyotes (all of which we have here) but in the getting of the chickens, some feathers are shed. The hawks cannot get air to pick up the chickens I've found and end up chasing them around on the ground trying to lift them up to fly away. I try locking them up in the henhouse earlier, but they are so miserable they now make a break for it to get past me when I let them out in the morning, and then stay wandering the yard and won't go back into the chicken yard. It is as if aliens are taking my chickens! These are the preditors I have, do you think any of them could sneak up, grab a chicken out of a pack of eight, and disappear without leaving a feather, just a whole lot of really upset chickens behind? We have black bear, bobcat, cougar, coyote, skunk, fox, raccoon, hawks, eagles. My yard is about 3 acres in a rural area of the Columbia Gorge, no neighbors right nearby. The chickens are in the yard immediately adjacent to the house. I've searched the property, my neighbors' properties, and don't find feathers. Just now the same thing happened again, this time my aracauna hen Goldie. So I've been losing barred plymouth rocks and aracaunas. Mature, heavy hens. My roo is an aracauna and keeps his hens together and is protective of his (formerly) 7 hens. Now I'm down to 4. So the question is, what can sneak up, attack, and get away without causing so much as a single feather to drop off my chicken???????
