I think today is the 21st day... but I could be wrong... I set a few eggs into my home made incubator on the 14th early morning. Several of them were dropped and cracked along the way but I have 2 left that I hope will hatch! After noticing my temps were swinging anywhere from 95 - 105 I have been very worried that they may or may not make it. A few days ago I received a hovabator in the mail and they've been in there now so hopefully the temp swings will be a thing of the past... if not for this hatch maybe for future hatches. Is today the 21st day? Am I supposed to notice "pipping" by now? Can I candle to see if they're on track? Oh man... I'm excited yet nervous.
