Hi and welcome, might be best if you can start here. https://www.backyardchickens.com/t/601352/little-giant-incubator-tricks/1000_50
Is a form for tricks on LG incubators. You can read the hole thing or start at 1003 and read till the end. Lots of people there to help you out.
I'm not really sure why your eggs are sweating. Did you put eggs that where cool (from icebox) and place them in a warm incubator? If so that's why they are sweating. Most people will set there eggs out in room temperature (71°) for at least 8 hours before placing them inside their incubator...
Well I always shoot for the lower 40's. But don't panic if I see lower. 50's. Best to weight eggs before putting them in. Then shooting for 3-4% per week reduction in weight.. It best to adjust for egg weight and air sack size than a humidity number. Will try to post a pic of size of air sack...
