I am hatching my first chicks ever and out of 8 banty cochins 4 hatched. One of the four kept violently flipping over backwards in the incubator, really knocking the unhatched eggs around. After about 24 hours the chick seemed to be walking normally so I moved it into the brooder with the other 3 chicks. About 48+ hours old the chick started tucking its head to its chest and flipping backwards again and peeping nonstop. It seems to calm when I hold it and will drink when I hold up to the water (I am giving it really diluted sugar water) and seems to eat a tiny bit when lifted it to the food, other than that it doesn't seem to eat or drink. It seems to be keeping its right eye shut and its left eye open (it has had both eyes open prior to this). Is it having a seizure? Or? Is there something I can do for it?
