I picked up 12 chicks from a local feed store Sunday. When we got them home, we noticed most looked ok, but 2 were not thriving. One of the 2 died within 24 hours, the second died last night. I'm still learning, but I'd reckon that if it doesn't thrive from the get go, something is wrong, and probably won't make it. Obviously I hope yours will be ok, just letting you know I just went through the same thing, trying to figure out what's wrong etc. Good luck!
