Hi, can you provide details on removal of membrane? My incubator struggled halfway through my incubation throwing everything out of whack now I have 4 ducks stuck in their shells for almost double the time. I opened the air sack portion so they could breath, moisturized the lining that was dried but there is still fluid in the egg, I see no veins or yolk sack. They have been like this for a cple days now.
