I have a 4 week old chick (one out of 13) that has a runny nose and seems to be week and shivering. It did drop to freezing last night but it was in the coop with a light and it's momma. Seems to be pooping and eating and drinking as far as I could tell. I brought it inside and have it trying to get it warm but it feels warm. Can a vet help her? is she doomed? Please help! any advice would be wonderful! thanks!
