I dont really look at hygros anymore! I look at air cells, and for hatching I know that I do exactly the same amount of water for each hatch with success so even there it doesnt matter, HOWEVER when I make my hatcher cabinet cooler I will need one as I have no clue how it will hatch, I am getting the following as they seem to be the most accurate....... see paste from hatching 101 article note the wet bulb hygro and how it works?
Sally I do have a question. I weighed, candled and marked air cells on all of the eggs I received last week. I'm planning to do what you suggest and go by weight loss and how the air cells are doing versus a humidity level. But I'm finding that hard because I'm day 4 now and since I haven't candled since the day I received the eggs will it be too late for me come Day 7 when I weigh and mark air cells again to make any adjustments in my humidity levels? Right now I feel like I'm guessing
