My first set of eggs weren't successful, so I pulled some eggs from the fridge. They had been in there a minimum of a week and half. Some were not fertile. I am on day 21 with 3 eggs. One pipped sometime today. I noticed around noon when I added some more water as humidity had dropped down a little. Baby is still peeping so hoping for an appearance soon. What is the normal time frame from pip to hatch? I just don't want to leave it without help and loose it. I am guessing 12 hours is standard but second guessing myself.
