I recently put a dozen eggs in my incubator, and only 2 eggs hatched
I kept the humidity at around 40°F for the first 18 days with regular turning. After day 18 I put the humidity to about 65% and left it closed except having to add water maybe every other day. My dad and I checked the the four eggs left and they were fully developed but died in the egg. Any suggestions on how to prevent that or how they died?
