Guinea eggs not pipping... day 29!

[Schelle]

This is my second attempted batch of Guinea eggs. I have a Hovabator and followed the Guinea egg sticker from BYC. Eggs were turned at least three times a day, temp maintained at 100, RH 25-30 using a calibrated hygrometer. Started lock down on day 23, reduced temp and have kept RH above 80%. Candled and weighed at days 10 and 23. Weight loss was closer to 14% overall. Of 17 initial eggs, 3 were fully developed at day 23. I'm at day 29 now with no pipping. All are viable according to float test but there is no movement and no sound. Are they a lost cause? Do I try assisted hatching? And what can I do to improve?

Never do a float test on viable hatching eggs. It is a good way to kill them. If you want to know what is going on, get a good strong light and candle the eggs.

I try to incubate my guinea eggs between 30% to 35% humidity. I know of people who have great success incubating at 50% humidity. For lockdown, I keep my hatcher between 65% to 70% humidity. I would not try to drive the humidity up to 80%.

If you closed the air vents to get the humidity that high, your eggs are probably dead due to suffocation.
