I also have a LG and as soon as they start to hatch, the humidity goes up. Every time I incubate, my humidity hovers around 16%. Hatch day is tomorrow and I have been trying to raise it a little. I put a straw in one of the vent holes and put very little very warm water in one of the wells. I don't want the humidity to raise much. One time I had several drown from too much humidity. That's why I dry hatch. The woman that encouraged me to dry hatch told me to throw out the hygrometer and do not ever add water,
I just can't. From now until Monday night, I'll be a wreck. My 5 yr old grandson spent the night last night and adjusted the temp. This morning it was 90F.
