Of the 24 chicken eggs that went on lockdown as best I can tell 16 have hatched. The first one hatched night before last. I still see at least three or four that have pipped. Everything I read tells me not to open incubator at all if you see any pips. But I'm worried about the first couple that hatched that they may be in there too long. Btw on a side note since lock down I increased humidity to 70% and each chick that hatching raises humidity level to around 82%... kind of cool since with all that humidity it's hard to see in there through the window because the moisture build up. So I know when another one or two have hatched!
