We just got a shipment of chicks today and noticed that one of them seems to be shaking and moves sideways and backwards when it moves. I did the Homemade Electrolyte Recipe that I found on the site but can't find what could possibly be wrong with the chick. Its head isn't pointed up and legs seem to be fine... any thoughts/suggestions? We've separated it from the rest of the flock and want to get the little chick better and back to its buddies!
