I have a sick chick that has been moved into a seperate brooder away from my recently purchased flock so it won't infect them. It is 1 1/2 weeks old and is sleeping alot and won't eat or drink on its own without me forcing it to do so. I have been giving it vitamin water to try and get it to be stronger. It can walk around on its own sometimes and chirp loudly when disturbed. Does any one know what might be wrong with him? What should I do?
