Thanks! That sounds like the way my scale works, so I'll use that next time I incubate.I use a digital scale that gives me grams as well as ounces. I weigh in grams, it is just so much more accurate for small changes in weight. I put a small stainless bowl with a folded piece of paper towel in it, put it on the scale, tare it to 0, and weigh the egg.
