We adopted roosters that were at the humane society and we've lost a few to predators since we let them free range. Today we were out and came home st dusk to find one upside down in the snow. We brought him inside, turned up the heat and put him in front of the vent. We was very lethargic and we are trying to get some water on his beak. Any suggestions? I'm terrified of birds, but my daughter loves them.
