I am currently on day 21 of my hatch with no pip not even an internal one. There is no movement in the egg that I see. Everything looks fine the air sac looks a little small. Also I did a float test and got good result's. could the smaller air sac be effecting my chick being able to pip? I know I am not spossed to intervene unless absolutely necessary, but if the chick is alive and cannot pip what am I spossed to do?
