Ok, I'm kind of a leave things alone, and if they are supposed to happen, they will happen type person. Again, this is my first attempt! I was trying a dry hatch, My humidity thin/temperature thing said I was at 34 - 36% humidity, temp at 99.5 - 100. I heard all the horror stories of bad readings, so I bought a second one - digital. It's been in for 2 days, and the temp says 99.5 to 100. But the humidity says it was 16. Original one still says temp 100, humidity 32. So I candled my 11 day olds. There are 30 plus eggs in there. I candled about 18. The air cell looks a LITTLE big on most, REALLY big on 2. There was movement in all but 1. Tomorrow, I will go get a 3rd and hope it matches one of the two. Is it better to error on the humid side, or the dry side at this point? The HAL eggs all have the right size air cell.
Thanks!!
Try calibrating your hygrometer... fill a shot glass with non-Iodized salt, add water til it stays wet but not above the salt and place it and the hygrometer in a ziploc bag and leave it for 12 hrs... it should say 75% humidity if it's correct, otherwise add or subtract to get 75% and that will tell you how off it is...
