I'm not an expert but comparing yours to the how to candle pics that are stickied yours look like they could be 15-16 days. I would try 35% and tomorrow I would check and make sure they aren't losing too much. And the next day. I'm a candling addict and as long as my incubator keeps and maintains my temp and humidity, and I wash my hands, I'm not hurting my babies. Mark your aircells to make sure and see progress. Believe me when I say I KNOW how bad it sucks to have zero hatches.
My hatch history is this: My 1st hatch with a still air was 15 eggs 3 hatched. Next hatch I tried the dry hatch and I think I was too dry I believe hatch #2 was 20+ eggs 0 hatched. My 3rd hatch was ?17 eggs and 1 hatched and I was using the 50% and I had not calibrated my thermometers or hygrometers and lockdown on day 18.
Hatch #4 15 eggs and 10 hatched. I got an analog hygrometer for a humidor and my WalMart digital hyrometer when calibrated by the salt are 6 and the other 8 too low. In the incubator they run 12 and the other 15 too low but I still use them too see if there are any spikes in temp or humidity. I also found out I was miscalculating my hatch day wrong, I was 1 day early. I candle every day even in lockdown as long as nobody was in the middle of zipping. Another wrong thing I did was when I put my fan in, it was blowing air on my eggs, now I have my fan angled where it points upward toward my bulb and the air is heated then circulated. I lay my eggs on their sides and turn them 3-7 times per day. I lay them on a layer of batting that is used for making potholders shiny side up. I stopped turning at day 18 large side of aircell facing up. If there is anything else I can think of or if you ahve any questions let me know but this is what helped me improve my hatch rate.
