I think you mean pipping. Sounds like you have had some quitters if they did not develop fully. It could be caused by many different reasons, temp too high or low, bad batch of eggs, type of eggs, not turned enough. Don't give up.
Yeah you mean Pipping - Pimping is a whole different sort of chick site! -
If it helps I just had a really bad hatch and only two chicks survived the incubator. Don;t give up - as the other poster said its probably a temperature thing. It is sad when that happens but sometimes it happens even when you get everything right too!
my bator stays at 99...i do not like it above that. and my humidity before day 18 is usually around 35-40% then I kick it up to 65% on lockdown. And i've had wonderful hatches. i've only lost 1 or 2 out of a 40 egg hatch lately.
ohh great, that makes my incubation probably worthless!
I have had my temps at 101-102 the whole time since I could not get it to stabilize at 99.5. It would just drop to 98ish and stay or go to 101-102. I could never get it between that and I figured a little hotter is better then a little cooler. ummm maybe not!
I did candle a few last night and they were moving around, lockdown is supposed to go into effect this Sat. night at 10PM.
