Ok. I have 2 mallard duck eggs in the bator one pipped in 3 spots 12 hours ago and no more pipping since. When I checked on them at 5am I swear I heared it peep but I'm not sure now it rolls around every once in a while but that's it. How long do I wait before it's in trouble?? My son is hatching them so I don't want to loose the little duck he lost his first two chicken eggs because we put them in with the duck eggs and they absorbed all their humidity so they fully formed but couldn't turn to pip the air cell so I don't want to loose anymore. Please Help
