I have 12 one week old baby chicks who are so healthy and then I came home after my trip with the kids to see Santa, and a baby was dead in the brooder! I have no idea what has caused this. It looked like all of them have been eating and drinking and of course pooping everywhere, I thought they were all healthy. Does anyone know why a healthy baby chick would just die like this? I have them inside away from drafts and a nice big heater bulb that they love to cuddle under and lots of baby chick food and lots of water.
