Tips for keeping humidity up while I sleep?

[Crazy Duck Lover]

I’m currently incubating duck eggs in a NR 360. I try to keep my humidity between 50-55% before lockdown. I’m only on day two, but I do a good job of keeping the humidity stable during the day, but when I wake up it says the humidity is 39-40%! Will this effect my hatch rate? How to I keep the humidity stable during the night??

so I take it you are keeping things stable by spraying the incubator every few hours.
Have you tried placing a wet kitchen sponge in there? - if you have the space to do so.
The aim is to increase the evaporative surface in the incubator so if the trays are full then adding a wet sponge will add a decent evaporative surface because it it very porous so lots of internal surface area that will add to the evaporation without having to spray constantly

Yes I keep it consistent by keeping the tray full every 5-6 hours. Thank you for your advice, I will try that!

It is the average humidity that matters. If you have 12 hours of 52% then 12 hours of 40%, then you have an average of 46% per day. I don't know duck eggs, but if that were chicken eggs, that would probably be just fine until lockdown.

I have the NR360 also. I can normally keep the humidity in that range by filling up the "A" port until it can't hold any more. It will hold a lot more than you think. If you pour slowly, it will keep going after the cup appears full. Then, I open the air vent halfway. I know that relative humidity matters, but my house is dry, and I only have to fill mine every 36-48 hours.

Thank you for the reply! That is great info and took a lot of stress off of me

Thank you for replying! The only thing is that I live in a very humid climate, so a table spoon of water will spike my humidity to 80+

Bummer. In that case, listen to the other posts.

You can also add a dry piece of sponge and it will do the reverse effect. It will bring humidity down.
