Shipped guinea eggs, 21 total. 10 never developed, 4 early death, 7 made it to day 23. Incubated at 100, 43% humidity, upright, circulated air. At lockdown they were moved to another incubator at 100.3 (several thermometers to back this up, with this particular one the eggs do best at this temp, below yields sickly babies and lots of death), circulated air, on sides, humidity 70% give or take. Two days later they were all dead. What'd i do wrong? I've had some ups and downs with my chickens, but most of my hatches from my chickens have a 90-95% hatch rate.
