I just got 15 chicks from meyer hatchery and when I opened the box i noticed one chick was in the corner and it looked dead. I noticed it was still breathing so I quickly picked it up. It breathes and has a heartbeat, but it is completely limp and only moves its head a tiny tiny bit every once in a while. I dipped its beak in some water and it drank a little. PLEASE HELP! Is this a heat, disease, food, or water problem? what should I do?
