I have done 4 hatches so far in my incubator, and this problem occurs in all hatches, to about 25-50% of the hatch. It has occurred with chicks from several breeds, and also to a Chinese painted quail chick, so I know it isn't a genetic issue. The incubator is a little giant still air. Temperature is set to 101.5 degrees. I turn the eggs 3-4 times per day up 'til day 18. (day 13 for the quail) Humidity is 40-45% the first 18 days (I cannot get it any lower, I have it sitting next to my dehumidifier as it is) and 70-75% after removing the turner. What happens is that the chick will pip a tiny hole big enough to breath through.... and nothing else. I usually attempt to help after the 24 hour mark. At this point, the chick is entirely shrink-wrapped, with blood trapped in the inner membrane as it dried. I wet the membrane every 10 minutes or so, and remove membrane that no longer has blood in it, though this is often difficult to tell and there's usually a few drops of blood lost. It's a long, tedious, nerve-wracking process. After it's all done, I apply some iodine to the navel stump, as I lost several of my first hatch to infections of the navel after helping them hatch. The chicks are usually quite lethargic at first, but perk up after a few hours. By day two, it's hard to tell who had trouble, and who hatched naturally. Is 70-75% humidity not high enough? Do y'all think my hydrometer is busted? I would rather not have to interfere, but I'm not about to let a perfectly healthy, 'lazy' chick die in the shell.
