I know you guys get this question a lot. I picked up my first flock of 6 Monday at tractor supply. One was chirping ridiculous amounts. Now that chick is barely alive. It's just laying around, won't eat, won't drink. The others started picking at it so I've been carrying her around in my bra. I've been making her sip sugar water every 20 minutes and I've tried to give her egg mixed with milk. She won't take it on her own. Her vent is fine, pooped earlier which was fine. She is so not developed like the other ones. They look like baby chickens and this one still looks like and acts like it's an hour old. What else can I do?
