I just unloaded my truck from a lot of stuff for my garden lol. I love the heat. My temp gauge is right beside my eggs so it's showing the temp at the middle of the eggs. The only bad part about this weather is I'm having to wet the sponges in the incubator every few days lol. No i haven't marked the air cell on them. I know it bigger than it was, but also more clear. Last time I handled the eggs to candle them was day 18. I'm not liking this incubator right now lol. These eggs are for my boys. They want to raise them as pets like their PaPa did. I afraid if I mess with the eggs right now I'll hurt the babies.
I wouldn't mess with them now, either. Really hoping they will hatch for you and the boys!
I just like to follow this chart to see if the eggs are losing the right amount or if I need to adjust the humidity:
So all my eggs have circles on them.
