My relatives found a young rooster almost dead lying in the snow a couple days ago. They brought him in and took some care of him for a day, then they dropped him off at my place since I have hens of my own. I made him a place to eat/sleep inside our home. I give him constant attention but I just can't figure out what's wrong. He likes to close his eyes all the time (even after waking up from sleep) and he likes to stand up. He doesn't have the greatest balance but he refuses to sleep laying down. I also have to hand feed him otherwise he just won't eat, and even that's a hassle. I'm not sure what I'm doing wrong since I haven't raised an unhealthy bird before. He likes to drink the water I have supplied but only drinks it when it hold it up to his beak. He also never really makes any noises, he just stands there quietly and doesn't move. Also, he fluffs up his feathers and buries his neck down as if it's cold in the house. Again, I'm not exactly sure what he wants, he just seems really sick to me. It looks like he just wants to rest some more but I can't leave him like that knowing he's probably hungry and thirsty. Although he is very young and I'm not sure how much they're supposed to eat at that age. My hens are almost 3 years old and they constantly eat and drink. Any help would be appreciated, I really want him to be healthy! Attached is a photo of him: After I took the photo he sort of just collapsed under his own weight, so I moved him to a place where he can lay down and rest.
