First time incubator here.... I set 7 eggs on 12/27. It looks like I have 4 viable right now. The first time I weighed them the weight didn't decrease so I stopped putting water in....that was a week ago. I candled and weighed today and can see weight loss but it's not consistent for all the eggs so I don't know if I should add water. I'm using a Brinsea mini advance and don't have a hydrometer. Here are the stats. Weights are in ounces for day1, day7 and day14 Egg1 1.8 1.7 1.7 Egg3. 2.6 2.6 2.4 Egg6 2.6 2.6 2.5 Egg7 2.6 2.4 2.1. 17% Egg7 has lost 17% already(if I calculated it correctly). Should I add water just for that one?
