Sorry I didn't respond last night! I go to bed early. I gotta get up at 4am. It should only take 24-48 hrs once they start to cheep. sometimes just a couple hours!!! It just depends on how thick the egg is and how strong the chick is. It can take 3 days. But not usually! Once they pip it is the hardest part. They are so close but it can still take a while. They have to work a lil, stop catch there breath and energy, then start again. Its amazing to think they actually can turn inside that egg. I couldn't belive the way they are crammed in there that they could even breath at all!
Good Luck and God Bless!
