This is a chick in a egg on day 24. She is breathing but there are no chirps to be heard. So we decided to crack the egg a bit so he could have some help and one day later nothing had happened! So I went through the egg shell, through the outer air sack and looked at the inner air sack. I can see the beak flat against the sack and there is still no chirping. He's been laying there all day and nothing is happening. I know he's not going to be able to hatch by himself but I don't think I can cut through the inner air sack as it may kill her. Please help!
