Okay so I'm a total newbie to this hatching thing. In fact, I'm in the progress of my first hatch. Two babies totally hatched out of seven and four eggs have pips! I have three eggs of my Olive Egger Nutmeg, three eggs of my Olive Egger Esme, and one egg of my EE Hazel in the incubator for a total of seven eggs. I've had to help two of Nutmegs eggs out of the egg membrane because they were darn near tough as leather. Hazel and Esme's eggs seem to be right on track and decent with the moisture level of the exposed membranes. Am I crazy or can certain chickens just have drier, tougher membranes or does it have to do with the age of the egg? Nutmegs eggs were a few days older than Esme's when they were put in the incubator. Thanks!
