I have 2 guineas that mostly stayed in the coop since it snowed several weeks ago. They decided 3 nights ago to roost in the tree about 100 feet from the coop and have not come down to eat or anything. We plowed a path so they should have a good landing area. Trying to coax them with food. Tried scaring them down. Nothing. Will they actually stay up there til they die? It's supposed to be subzero tonight. Frustrated!
