I have a chicken recovering from a dog attack, and the vet said to keep her separated from the rest of the flock (which is actually just two other chickens) for a couple of weeks while her wound heals. I've got just a small backyard coop and run, and it's down in the 20s at night here (actually the thermometer read 12 this morning). I'm not sure how to separate her while still keeping her warm. Would love any suggestions!
