A bit scary taking out a full turner. I e used a turkey basted in the past to suck out water from the lower troughs and not had to remove the eggs at all.
Considering that so many members have had good hatches with variable humidity settings, perhaps humidity is not as critical as we thought. There is clearly a large tolerance for humidity levels.
I have been running 50% humidity through the turning cycle and when I stop turning uping the humidity to 75-80% and opening the plugs. Sorry, but I've never heard that high of humidity.
I run mine at 40 percent until I stop turning then bump it up to around 70 percent. I just hatched 40 a couple weeks ago using this method. Works great for me.
I have always hatched chickens , this will be my first quail, I know with humidity that high chicken eggs wont dehydrate enough and the chicks drown in the shell.
The only reason I was wondering is the lady I got my eggs from said she even mist her eggs lightly with a water bottle every couple days and it creates higher hatches in quail.
I also run a homemade incubator not a store bought one so it has air holes open all the time I never plug them, I have 132 eggs in it right now and I am around 77-78% humidity. Everywhere I look I get conflicting info so I am kinda of confused with the quail deal.
I really think that you have been given bad info. Please DO NOT spray your eggs. This is bad on so many levels I personally feel. Humidity is something argued by many but I have never heard anyone go that high. Little giant incubators have two troughs for water. One to fill constantly and one to fill the last part of the hatch. Not sure what you have but you might even read your instruction manual for that perticular type.
