I don't know what is happening. My chick had to have an assisted hatch because it was stuck halfway through the unzipping process. There was no blood in the membrane and the egg yolk sack had been absorbed. My chick has started rolling around the incubator having a sort of seizure almost. Also chirping loudly with it's eyes closed, and curled up in a ball almost like it was still in the egg but stretching out occasionally I don"t know what to do. Someone Please Help!!
