I'm cooking 16 this trip; I'll also be surprised if any hatch. It might help if I knew how old they all are. I found 2 hidden stashes of eggs; over a dozen total. I put them all in the incubator, just out of curiosity. It's all set up out in the new building. Temp's held steady from the beginning; RH is all over the map. Wanted to see if I could successfully incubate out there; I think I have my answer. If anything hatches, it should be around the 15th.
Good luck!
