So all my eggs pipped (sp?) last night around 7-8pm on the 19th day of incubation. I took the incubator off of the auto-turn cradle and shut the vents to 1/3 open for extra humidity. I could hear the chicks in their eggs and all was very exciting. It's now 7am, 12hrs later, and nothing is happening! Is this normal? Did something go terribly wrong? I feel kind of at a loss....... any advice would be sooooo helpful.
