This chick hatched 11/1. It had a balance problem at first like the others but it continues and is not getting better. It loses its balance very easy and falls to one side and waves its legs wildly to up right it self, overcompensating and falling on the other side. It then lays there with legs out steached with a slight tremor. Once its calm it gets up and walk normal for a bit. It eats and poops normal. Only one other chick had this shortly after hatch and only lasted a day. Other chicks not picking on it but try to help and snuggle with it. Ive tryed sugar water, vitamins and electrolytes. Oh it was the last to hatch. What could this be?
