Same problem here.. I'm on day 18-19.. most of the incubation period the humidity was reading 62-65%... It's up to 69% now.. just a coincidence since we got so much rain..
I'll let you know how the hatch goes.. I have 18 in there. Candled one of the five eggs I took from the fridge and I could actually see movement of the beak or toes! I only candled a few.. was having trouble seeing in the others out of the fridge, except one I'm pretty sure didn't develop.
