Duck eggs, forced air with auto turner incubator, 99.5 degrees, 57% humidity, candled alive amd moving through last candle just before going on lockdown. Increased humidity to 65%. Skip to day 29 and 1 egg wiggled. Day 30 nothing. Day 31 candled with no movement so I opened the eggs. All had died in shell but had not absorbed the yolk, looked positioned correctly. See photo:

I don't understand what I did.
I read this link and scrolled down to where it listed causes for "no pip, dead in shell, yolk not absorbed" and it listed several reasons.
https://www.backyardchickens.com/a/egg-failure-to-hatch-diagnosing-incubation-problems
"Full term embryo, did not pip, dead in shell. Eggtopsy shows yolk sac not absorbed, or only partially absorbed. May be some residual albumen (egg white).
- Inadequate turning during incubation, especially during the first week, resulting in decreased embryonic membrane development and nutrient absorption."
- Humidity too high during incubation, or after lockdown.
- Incubator temperature too low, or too high.
- Nutritional deficiencies.
- Hereditary.
- Disease in the breeder flock.
- Eggs stored too long prior to setting.
- Inadequate ventilation."
So how did I kill them? How do I keep from killing my second set that's incubating now. I don't want to kill any more.
