I need some advice.... I just recently hatched 7 chicks out of 39 eggs. Which doesn't sound that good to me. After examining a few of the eggs that didn't hatch I noticed that the membrane was sucked onto the little chick inside. So I figured my humdity was not high enough. After placing extra cups pf water it still didn't seem to rise above 50%. Do I need to leave the red plugs inside the air vents inorder to keep the humdity up?? I want to get the humidity right before the 20th when my other batch goes in.
I am using a Little Giant- Still-Air.
