I have 38 Guinea eggs in a Farm Innovator circulated air 4200 Pro Series with an egg turner. The eggs have been in the incubator for 9 days. The water evaporates completely every day and the humidity stays between 57 - 60 degrees. The humidity doesn't drop below 57 degrees until I open the incubator.From what I have read on the internet, I am supposed to lock down the incubator on day 23 and increase the humidity to 65 degrees. If the water completely evaporates, how can I increase the humidity without opening the incubator, and adding water. I realize that I will have to plug the openings to increase humidity, but what about the water.
