My baby pipped externally within 24 hours of hearing her inside the shell peeping. Once I heard her I pulled up a video of baby chicks peeping on youtube on my phone and set it atop the bator and played it periodically and everytime she heard that she would start peeping and moving, I'm sure it gave her the motivation to move.....lol after she pipped it took something like 12-13 hours before she started zipping. Good luck, I hope they hatch out ok for you!Newb question: how long should it take from internal pip to external pip? I've read up to 24 hours before hatch. Does that mean 24 hours before pip, too? I hear a strong peep just twice last night; figured the chick went to sleep. This morning, (I've been up too long...) I didn't hear it, so I used the flashlight to shine on the eggs. There was a very quiet peeping after a while from the egg in the back corner. Should I (or rather, at what point) be concerned? This is a legbar, ae the shells harder? Thankfully, I have things to do this morning, otherwise I might be hovering! I'll check back in around lunch hour (pacific).
