Okay today is day 28 my teacher who put hers in at the same time using a hova bator had hers pip. But mine have not piped. I see one oddly air sac that has a protrusion in it. And I can see movement in one. What do I do the temp it said on both my digital and anolage thermometers said. 98 but after i sprits them with water they got cold. Any ideas could they be late bloomers? BTW my teacher did not spritz hers so her humidity is not as good as mine but hers ran hotter i think at 100 the whole time.
