So I candled my eggs for the second time on Day 14 and it seems (to me anyways) that there are some wierd things going on. First of all, I can't see into some of the eggs at all...I'm assuming this is b/c the chick is big and taking up a lot of room? Next, about 1/4 of my eggs seem to have a HUGE air cell that is at the big end, but then kind of wraps part way back around the side of the egg. In some of these I can see the chick swimming, so I know they're still viable. Any ideas? My temp and humidity have been good the whole time, so I don't think it's that. I'm new to the candling thing, so maybe all this is normal and I'm just clueless. Any ideas are appreciated!
