Okay so I set on the 27th late in the evening and nothing yet. Temps are good, humidity was touch and go in the beginning but I have it pretty well controlled now.
The only thing I can think is that when I bought the “hatching eggs” from another homesteader I got them home and they were very cold. I think she may have collected them and tossed them in the fridge? I let them sit at room temp all day before I set them, and there is definitely development. I just took one out and tapped and heard some scraping around inside.
Could the cold storage have slowed things down?
