This is my first time hatching, and it's been a headache. I bought a Little Farm 9300 incubator at yard sale and couldn't wait to use it. I've read hours and hours of "how-to" articles. I mostly struggled with calibrating temp and humidity, but have done everything else as by the book. It's now early morning on Day 22 and I don't see any pipping. I may have "cooked" these guys while trying to figure out the temp/humidity calibration. I'm pretty sure my bator is totally off (at least that's what the 3 alternate readers say that I put in the bator.) Any suggestions? At what point do I throw them away?
