It has 4 large vents, I think the most I’ve ever had to close at any time be as many as 2 and that was back in high dry summertime.... if I closed all four we’d be looking at near 100% humidity. So I have to close a couple partially to adjust the humidity. It’s just how it works.
The incubator they are in has too many moving parts for my liking.... I can’t remove the auto turner I can only stop it turning. Its instructions also advise not using it to hatch in - so I’ve just believed them! The hatcher is way more suitable for them to live in for the first few days & it does work well.
Kiki - What level of humidity would you suggest? Adjusting humidity isn’t an issue & it will still have plenty of ventilation.
