The porosity of the over sized egg was probably much denser and did not allow as much moisture to leave the egg.I had 3 other healthy normal sized chicks from the same clutch of eggs. All their air sacs were also normal size. I initially thought she was a bad egg taken over by bacteria inside but I was too paranoid to toss it (thank goodness). She was the biggest chick I have seen and her egg was on the smaller side with this being moms first clutch. None of the other babies I've hatched over the years came close to her size. I didn't have to help her hatch. She pipped and was out within a few hours walking around in the incubator. I kept my humidity at the same levels I always do, and I keep a secondary thermometer inside as a back up that tells both temp and humidity just in case the unit is ever wrong. I have been massaging her neck since she was born, she las learned that she likes it, lol, and she has been getting the extra liquid vit e steadily over the last week. But she is starting to improve and we will definitely keep trying and hope she makes it. My husband has named her Scooter.
