I have just started (FINALLY!!) my first batch of eggs. I have 14 in the incubator....yeah!! I have a Hovabator Genesis 1588 and have followed ALL the instructions. Does anyone have a good idea of how frequently I need to check the water in the unit. I don't want to open it daily if its not necessary....especially since they scare you to death about too much temp. fluctuation. Thanks in advance....
