I have been using weight loss to monitor humidity. My only egg in there has been weighing a bit lighter than expected based on set weight, so I have been keeping humidity high. But the air cell is definitely smaller than target for this point (day 19). I am guessing weight is more precise, but what would you suggest when they grossly disagree? This is a cayuga, on day 19 of incubation, forced air. Embryo seems bigger than I would expect, as I could only see one small pocket not totally dark, but I could see movement at least. Thanks!
