I’ve found that chicks who are particularly goopy and then dry crunchy like that tend to all be weak starters. My suspicion is that they broke the yolk sac before it was all the way absorbed, inside the egg, and the egg goop coated them which makes hatching more work, and they’re doing it with less gas in the tank so to speak. I’ve had good results with putting them in my extra bator with a small food and water dish, and I give a drop of nutridrench every few hours, sometimes with sometimes without water mixed in.
