3 more have internally pipped lol, lots of early birds. 6 in total now.I don't think you need to panic about the air cells. I think there is a wide range of what can be normal. I've had hatches with huge variations in air cell sizes and in the amount of weight lost and they all hatched fine. I think a lot of the time they don't draw down until the last minute.
Internal pips on day 18 is also not that unusual. You'll get a few hatching on day 20. Exciting!
