Don't give up hope just yet. We had a young d'uccle pullet last January that went missing- only found a pile of feathers after dark when we were putting everyone up. My father and I stayed out for an hour in 20 degree weather searching but didn't find anything. Late the next morning (nearly 11), my dog went out and started digging at the woodpile beside the coop. Wouldn't you know it? Our silly pullet had escaped the predator, survived the night and cold, and was still alive! Today, she rides around on my shoulder whenever I'm outside.
