Thank you so much for your reply!From my understanding and experience, the humidity level is what controls how large the air sac gets. It's a balancing act that is easier to predict if kept fairly consistent. I don't believe it crucial hour by hour until lockdown. After lockdown, the higher humidity helps the shell soften and keeps the babies moist and lubed for hatching, as they can take some time. It's a balancing act that needs to keep the destination in mind more than any particular point along the way. I do dry hatching because I live in Florida and it's humid most of the year. I only add water if it drops below 30% and full water for lockdown. My experience only goes as far as chicks but know they are very similar. Ducks can be much more difficult but keep trying!
I’ve heard a lot about dry hatching but I don’t know if I can start that if I’ve already started with 45%, which dips to 30% overnight.
For awhile I was actually setting my alarm to wake up every 3 hours overnight, but it became too much. (I have 2 young children)
I’m currently at day 21 and 19 with 2 of my eggs and I’m so nervous every time I candle them because I just cannot get past days 15 - 20.
As of this morning my oldest one would have been at day 22 today, but I candled it this morning and it has passed away too.

I’m just devastated because we very much want to add to our little group.
This is my girl’s first clutch, she never went broody and has been dropping eggs everywhere since January 23rd!! So I had no other choice then to intervene, plus I am in Connecticut, so it’s just too cold even though we bring them in when it goes below 35 degrees at night.
I just can’t imagine what I’m doing wrong. I’ve read everything I can find regarding incubating Muscovy eggs and most things I’ve read contradict each other, so it’s very confusing for me, as I had no idea Muscovy’s were so difficult to incubate. I’ve heard a lot of people have trouble with them as well.
I have pretty much lost all hope that any will survive.
Would you have any suggestions or advice on what to do?
The temperature is 37.6 - 37.8 C and the humidity is at 45%, but dips overnight to 33 - 37%… Could that be the problem? I just cannot keep the humidity constant overnight and getting up every few hours is exhausting.
I hope to hear back from you.

Blessings,
Amy
