I have a few runner duck eggs I've been incubating and two are actively tapping away and working on their external pip while one hasn't shown any sign of activity. They all internally pipped fine but it's been over 24 hours since then. I went ahead and put air holes in all of them. I chipped away a little at the air hole of the one I'm having trouble with and I'm not really sure what it's supposed to look like inside because I've never had to assist besides adding air holes. Is this duckling shrink wrapped or does it look normal? Should I keep the membrane moist with a qtip? Also the hole isn't quite as big as it looks in the pictures, just enough to see inside good.
