Have you calibrated your thermometer? What kind of incubator? Give them more time. They're definitely not ready yet. I'm guessing your temp was actually too low.
Aw, I'm sorry. He may have been a weak chick anyways. If he was malpositioned that's definitely a problem too. Was there any yolk left? I agree, how's the other one, @Maisier ?
It's very rare for chicks to drown. It's only when the air cell is intact, and the chick internally pips into it, and drowns in fluid. That is only if your humidity was too high throughout incubation. Like, 60% plus.
Have you checked the temp in your incubator with a calibrated thermometer? I'm guessing your temp is way off. Can you post a pic of the eggs? I'm guessing they won't be ready for another 2 or 3 days yet.
