I have a three week old silkie (mixed) his (we just call him a him ( named Charlie. He's a indoor chicken and rides in the semi with us everyday. He has medicated starter feed and fresh water. I woke up to find him acting strange. He won't hold his head up, rocks, won't drink or eat, runny poop, won't stand, losses balance. I've been trying to give him Pedialyte. He took a little bit but doesn't seem to get any better. He was fine when we went to bed. Can anyone help me?
