So one of our hatchlings had hatched about 24 hours ago but can't or won't get off its back! It gets around the incubator, lifts its head and seems to be quite lively and feisty. It's sac isn't completely absorbed yet, much more so since it first hatched, and its finely just starting to fluff. Any suggestions as to what's going on here? We are giving it water/electrolyte mixture and its drinking well. I'm speculating mushy chicken disease but not quite sure. Would love to save this little chick!
