OKAY. I have hatched chicks before and never had this happen before. (And it couldn't have been better timing actually, for my hen.) I know exactly when they started, they had a false start but including that day they should have actually been delayed. (She sat on them a few hours then got up and didn't sit till like a day later and i kept them at room temperature) But even with that added to it she's 3 days early with her hatch. All eggs have pipped on 19th day and 3 have fully hatched out, perfectly healthy and chipper. What gets me is they are all different breeds so it's not breed specific. First out was an EE out of a green egg and the next two were brown eggs of different colors and the chicks were blue and the other black and white. It's probably normal, but I haven't had it happen this early. How about everyone else? I've heard of a few days late but early?
