My chickens free-range for an hour or two a day, usually in the afternoon. I let the chickens out at 2:30 and sat out on the porch steps for a while watching them. I went in for about 15 minutes, and came back out at 3:00 with some sunflower seeds. One hen is gone. She was an EE, but fully grown. The other chickens and rooster are not acting skittish, and I could find no feathers and no tracks in the snow (which is only about an inch deep). I looked in the woods near the coop, thinking maybe an owl or hawk could carry the bird a short ways, but found nothing. Can hawks or owls carry a 6 pound bird a long way? I guess I will have to stop free-ranging for a while, because I'm sure the bird (or whatever it was) will be back. I would've thought that this white EE would have had some camouflage advantage in the snow.
