After breaking open my late eggs i found the first two were duds. Must have stopped developing around day 3ish. I expected the same from the Maran eggs. I took the top off first - so that the membrane is still all intact, I basically exposed the air cell. I used a sponge to dampen the cell to see through it, the chick is inside and seem okay, i can see a little yolk to be absorbed on one side but other than that it seem fully grown - as far as i can see. I have put the sponge back on top to keep humidity in and put it back in the incubator. Will it still hatch? The membrane is all fine and not open or anything?
