how much water needed in bator

If you can go to Wal Mart you can buy something there for less then $10.00 to check your hum. They are by the lightbulbs. I can't tell you much about the 9x9 tin tray with water in the center of your bator. That seems like a lot to me. Don't you have a place in the bottom of the bator to put water?

 

in my freez-a-bator forced air I only have 1 pan about a 6x6 and it keeps the humidity at about 52 -60% I fill it once a week when I add or remove eggs..in my hatcher still air frig I use a 9x9 cake pan with 2 wet kitchen towels and it stays around 80%..
Hope this helps..... You can click on my website link on the left and see my record for a recent hatch.

I bought an Accurite thermometer/hygrometer combo from Walmart for about $7. I have a still air bator and it's very tricky to get the humidity just right. With a tin that big, your humidity will probably be way too high.

 

There are little troughs in my incubator and I just fill one little one with a little water from a turkey baster and it's always just a tad bit higher then 50% I think if your filling 1/2 it would be to high of humidity. You can cover surface space by folding tin foil and placing it under the wire. It will lower humidity within a 1/2 hour

 

Quote:From the info I've heard from so many people the 1st 18 days the humidity is to be 45% to 50% & the last 3 days it's to be as close to 70% you can keep it...like a range from 70% to 74%. That's what I've read from experienced hatchers postings here on BYC.

 

You need a good hygrometer and thermometer, in all honesty the guessing game will be nothing but problems.
