Yet again, I am here with incubation questions. So, I put 12 eggs in my bator and their due date was Monday, but only one hatched on that schedule, the other 11 are still not hatching. But what is weird, is when I candled them on the 18th day, all but two were kicking and squirming, so I would be surprised if that many were clears. Could they really all be this late, and should I give up on them!? Please advise!! Thanks!
