I check my eggs once a day, it's day 20 and a few of them have huge air sacs, like one side has a huge dip, and those ones have internally pipped. I can hear peeping if I tap on them. Should I expect to see any shell pips tomorrow? Will they do it overnight? I'm so excited!
Also what made the air sac have a huge dip all of a sudden?
