I have two call duck eggs in the bator. They internaly pipped yesturday, this morning the first one externaly pipped. It is now after midnight and both eggs now have a circle of shell off but the skin (not sure what you call that) is white and i can see the bill trying to come through but they seem to be getting tiered. I have been spraying them with warm water. Do i open the white skin so they can breath cause i don't want these ones to die too. Help me if you can. Thank you very very much. Angie.
