I'm on day 17 and I just candled a few eggs. Noticed that some were mostly all chick with very little air cell (is that the right term?) at the pointy end. Some did have bigger cells. What does this mean? I have a LG still air and have been running consistent temps of 101-102 w/ humidity 42-46%. Is that bad? Edited to add: these aren't shipped eggs; they are from our own flock.
