I have read up so much on this great little incubator, and am thrilled to now own one I believe I will be putting some eggs in it on Friday already! I have two quick questions though. Is it better to set the eggs in egg cartons than to use the holders that are supplied? I will be manually turning if it matters. If the egg cartons are better to use, how exactly do I set them? Also, does anyone regular weigh the eggs to check humidity, or is that something that isn't normally done? Thanks in advance!
