Dry incubation advice

[Banjosan]

I read the article in the learning center "Dry incubation". It sounds like dry actually means around 50% humidity. I have a brinsea with a humidity pump. Does anyone have any thoughts on this matter. I'm thinking one needs to keep humidity in check and not drown the eggs. those styrofoam bators can really get humid.
thanks for your thoughts

I have no experience with dry incubation, but I remember reading some one saying dry incubation for chicken eggs was 30 percent humidity and then going to 50 percent on lockdown. I could be wrong though.

I just did my first dry incubation and kept my humidity between 25 and 35% during incubation and upped it to 55-60% during hatch. I don't know how the humidity pump works, but all I did was keep two calibrated hygrometers in the incubator, ran it for a few days before setting my eggs to see where the humidity fell without any added water. Then I added a little water to see how high it jumped to gauge what I would have to do come lock down. Once I was satisfied, I set my eggs and only added about 1/8 cup worth of water into the smallest available well (less surface space so only a slight adjustment to humidity which is all that was needed at the time) to up humidity twice during incubation and then again for lock down (which I used all three wells to up the humidity where I needed it).

I only had one chick hatch out of 12, but I don't think it had to do with my humidity. I think it had to do with the removal of a fan that had been in the room as all the chicks that died did so during lock down when the fan had been removed.

I hope my rambling makes sense.

Edited to add: This was also for chicken eggs. I don't know how this all translates to duck or other eggs.
