In your experience, why would an egg not hatch? I have 10 Buff Orp eggs in my incubator, on day 17 I did a final weigh and candling before lock down. Everything looked great, I even saw a few of them moving in the shell. On day 20 one hatched, but nothing since. Today (Tuesday) is day 21, but I have not heard a single peep out of any of the eggs. I moved the one baby out today for a few minutes to get some food and water, but she was not happy so I put her back in the incubator where she seemed more comfortable and went back to sleep. I know I have a few more days before the eggs may not "hatch", but just trying to locate some info as to why a chick may die in the shell. Thanks. Oh, the only other info I can provide is that the eggs were 2 days old before being placed in the incubator.
