At about 9:30 last night 3 of my silkie eggs were starting to pip. It looked like they were just barely cracking through the shell. This morning one of them had pipped enough that I could see the color of the baby; the other two look EXACTLY the same. I heard peeping around 5 am a few times although it sounded a little weak to me. Since that time there has been no change at all. How long does it take from pip to zip to hatch? When should I start worrying?BTW today is day 20. ONE IS HATCHED!!!! He's just laying there and not doing anything. He was chirping like crazy when he 1st came out but not anymore. Of course I was not home to see it but I called home and could hear him. Is he just tired or could something be wrong? Do I pull the vent plug? Still have others in there that have pipped. BTW this is one of them that was not doing anything...the one with the biggest pip has not changed at all.
