Greetings! I'm a first timer at incubating coturnix quail. I have 8 eggs that are all definitely fertile and the babies inside of them are alive and kicking. Today is day 15. I did a final candling yesterday and noticed some inconsistencies. First, the size of the air cell is different egg to egg, but the conditions in the incubator have obviously been the same for each of them the whole time. (40% humidity day 1-14, about 55-60% now). Are some slower to develop? Some were pretty big, what I'd expect to see on day 17 (from the diagrams I've seen. I'm no longer bothering the eggs with my prying eyes). Also, while not the same pronounced saddle shape you sometimes see, I've noticed that some of the air cells are uneven. Instead of being circular, they'll have a sort of "bulge," though not a significant one. Is that something I need to sweat? I mean, probably nothing I can do to fix it now, but should I lower my expectations? In either case, excited for whatever the outcome is. I feel like a kid on Christmas eve. I keep walking into the kitchen and singing a song I wrote titled "Please hatch soon my little bird fetuses." The words are pretty easy to learn: Please hatch soon my little bird fetuses I want to see your peeping faces If you don't hatch I'm gonna be so mad But not at you 'cause I know it's not your fault I hope it's helping.
