We picked up our chickens from the hatchery on Monday and this little one seemed ok. It's now 4 days later and she can't stand and is very weak. I've been holding her all day to keep her close and warm and have given her watered down yogurt through a dropper and also some water with vitamins in it. It's not helping. She keeps falling asleep and having a hard time waking up. I'm able to force the vitamin water and yogurt on her a bit, but she isn't eating on her own. She will chirp occasionally and she has been pooping. She was walking around and acting normal yesterday, so I don't know what is wrong or what to do. Anyone have any ideas?
