We have eight chicken eggs we got from a neighbor, various breeds. This is our first time incubating. I candled the eggs tonight and one of the eggs, I think it is a banty because it is very small and roundish, seems like the air cell fills up half the egg. This just happened this week as it was fine before. I just read that small eggs dry out quickly, so I guess this is the problem since we have mixed sizes. So, i'm guessing the chick probably isn't alive still?? Should I remove the egg, because of the possibility of rotting, or should I leave it?
