Try water.On another note, the two littles aren't eating or drinking and I've dipped their beaks. Their siblings are eating and drinking and they watch. Suggestions? I have ND but don't like to use it after a bad experience of a chick aspirating despite careful attention.
I'm thinking you might have over heated them with the hand warmers. Temps in the 70s is not too cold for chicks.
Drops on the side of the beak...don't force anything.
