So I'm getting my LG ready to hatch some 19 day old eggs. I just put the water in and I'm waiting for the temp to stay steady for a few hours before I put the eggs in. But my question is, I want to try to keep the humidity around 60% at this point, correct? And on top of the LG, there are two red plugs, am I supposed to remove one or both of those during the hatching phase? The babies are getting very wiggly in their eggs... I think it's only a matter of time till they pip!
