OMG I'm so glad you found it! Do you have a brooder with a heat lamp so it can regulate its own temperature? Or maybe even a heating pad you can put at one end of a brooder? I would continue to try to give it a little water every hour or so if you can. Make sure the water is warm since its already chilled. You might also try putting some warm water on a bit of food and see if it can eat that. It might be easier than dry crumble.
