Crossing the Road
if it has chirped, it has internally pipped- I expected to see the internal pip with my ducklings, but I never did see the classic beak in air cell. For me, I could just tell from them chirping/tapping.Yep, I just read through it last night. So about 18 hours ago, I candled it and saw it's heart beating and heard it chirp. However, I didn't see anything that looked like the internal pip from that article, so I'm not sure that has even made it that far yet.
So we can estimate that the chick internal pipped around 18 hours ago- So it is up to you, if you feel able, you can make a safety hole (no bigger than a pin hole, usually made by gently twisting the tip of a screw against the shell until it eventually makes a little hole) in the air cell for baby to breathe better- or you can allow nature to take it's course, or wait a little longer before intervening.
If it were my egg, I would probably candle to see how she's getting on, and then make the safety hole within the next couple hours.
