Plugs must be removed to have enough air flow-- as the eggs reachthe 18th day , they use more oxygen, and then when internally pip, the level of use increase more and of course once they hatch they need huge amts of oxygen. Hende the need for good air flow and remove those plugs at day 18 before internal pipping. Some LG users throw them away, I still have one.
YOu can choose to put hem in an egg carton ( bottoms cut off) for hatching , just be sure to check for those that externally pip at the bottom-- they cannot hatach in that position and need to be turned over or then lay on their side. I started by laying eggs on their sides originally . NOW I keep the eggs the same from incubating to hatching-- some discussion has revealed that this gives the best hatch rates.
Dont be afraid to open the incubator a nd check on the eggs-- "lockdown" is a mis nomer and you can go in. Be aware of the humidity and to keep it up , especially if an external pip. SOmetimes they dry and the chick cannot proceed. Especially if the feathers dry to the white papery membrane.
Good luck.
