I currently have 10 bantam eggs on day 13 in my LG styrofoam w/ forced air. I have a Springfield digital that reads temp & humidity....and an egg-o-meter. I checked readings on both of these before starting in a larger incubator for 2 days & both are correct...matching read-outs on those. I'm doing a dry hatch & humidity levels are perfect. Haven't thought about it when candling...all are developing. Then duh...last night when candling which would be day 12, I realised the eggs aren't as far along as they should be. I checked out some of the candling pics here just to be sure, & they look more like day 10 eggs. My temp readings are 99.4 on both the digital & egg-0-meter (reading outside temp on egg-o-meter)....BUT...when I switched over to INSIDE temp of egg-o-meter, it's reading 77.7 So...at this point, do I up the bator temp to get the inside egg temp right???? Or do I just let it ride as is & expect a slow hatch?? Suggestions??
