Hello just wondering how long generally is the time between internal to external pipping? I know it's longer than chickens. I'm so impatient so I'd like to not worry they are running out of air in there. They are buff Orpington duck eggs and we are on day 27. Lots of movement and most have internally pipped since last night. Its currently next day afternoon.

will do!
Its morning Australia here. There was so much movement last night I expected to wake up to at least one external pip. They sure taking their sweet time. Its, been about 36 hours since first internal pip. Day 28 now 
(pic from other day)
had me worried as was first to internal pip but wasn't moving a great deal compares to others...
