This batch is hatching in a Farm Innovator still air. I have hatched in this incubator before. Usually since it is still air I have hatched at 102. I have it at 101.5 for this hatch, just for something different. So this may be why they are taking their time. Also day 21 starts this evening, even though I had posted in the ams.
I did candle, most are not yet in aircell, so they may hatch on Wed. but I do have some in the aircell that will hatch today.
