Have just relieved an order of ten chicks. Two of my white rocks aren't quite 100%....one seems very uneasy on her feet and the other is limp, lethargic and barely doing anything. I've fed them both some sugar water from an eye dropper, and they have both pooped already. The other 8 are chirping and moving around, eating and drinking. Any thoughts on the two that are not quite 100%?
