Hummmm... good question. I dont know, but I do have 4 bantam eggs in the bator, havent seen any movement from them yet, but 4 BO eggs are wiggling and its soooo cool to hear their cheep cheeps
17 chicks and counting... several are zipping and the rest are pipped.
I did open the incubator up because the humidity was climbing to the 90'S! I have read too many stories of baby chicks drowning so I hope I didn't ruin the chances of the rest. Humidity has gone down to 80 and I might open it up again... unless told otherwise. LOL

I have been reading that it is not only about the humidity but also the CO2 that builds up. I will look for the post and past here if I can find it.
This makes total sense to me. Biologicly speaking there is always something that causes something else!
Thanks Sonew 123 for the heads up on this.
read this and youll see why Im saying dont open until tomorrow
"Anyone ever tried to make an incubator that you can put your hands into? It seems every hatch I read about someone has to open the bator for some reason during lockdown. The issue from what I have found is not just temperature and humidity which can be replaced fairly easily. but the Carbon Dioxide is released form the bator as well. the muscle spasms that cause the chick to hatch stop when the carbon dioxide is released. I was thinking yesterday about attaching a Co2 bottle to a bator and then you can put it back in if you had to open it for any reason. of course this would require knowing how much is enough to add. from what I found out it goes something like this. Chick is in solid egg and Co2 levels rise causing muscle spasms that do three things. one they cause the neck to spasm and this causes beak to pip. stomach spasms drawing remainder of yolk into chicks stomach. muscles in legs spasm strengthening legs. okay so this goes on for say 24 hours until the beak finally breaks through. this hole gives the chick a fresh dose of oxygen and the spasms stop. this helps explain the pip then nothing thing that a lot of people see. at this point he Co2 levels in the entire bator begin to increase until they reach the point that spasms begin again. it is exactly during this period of time that Co2 levels are building up that most people get concerned and decide they need to open the bator for this and that, and help with this and that, and add more water and whatever. sometimes the chick never starts to spasm again so never zips as it should. And opening the bator is removing the very thing it needs to get started again and you would very likely never suspect it. set a can of soda in the bator as a pip and zip primer."
