An egg should loose 11-13% of it's weight from laying to lockdown. Divide that [11-12%] by 3 and you will get a weekly average of what the eggs should be loosing.
By the way- it wasn't a dumb question, and despite what people say, I've seen some questions that make you go HMMMMM?? lol
Yes, some are slanted and some are more symmetrical. Makes it hard to judge sometimes.
i can definitely say that these air cells are better than the ones from my last hatch. i realized way too late that my hygrometer was not accurate throughout the entire incubation, and comparing these cells to those, i can now tell that the first batch were too small. there was a great big jump of cell growth from day 12 to day 17 today, and even a pretty big growth from what i remember being on there 2 days ago. so i am going to guess that's probably good! if i compare the 5 eggs, 2 of them are either more centered or are just slightly smaller than the other 3, but are still bigger than the ones i had on my last set.
do you weigh them with a food scale? or a more of a science lab one? with such small hatches, that might be something i can try in the future, especially when the eggs are meaningful (like turkey eggs, holy moly those can get expensive).
and man am i glad you didn't think it was a dumb question. i see people say it all the time, check the air cells, and never once, anywhere, have i seen any nice clear cut guide on how to READ air cells or what is good and what is bad, because, i think you're right, it's pretty subjective!
