I'm hatching my first duck eggs in about 16 yrs. My first hatch is 10 indian runner duck eggs (to get back in the swing of things). Eggs were overheated briefly to 118F a week ago when temp control jammed although obviously eggs didn't reach that temp internally and I was quick to fix issue. The eggs didn't start pipping until late day 28 and it's day 30 today. I have 6 eggs pipped out of 10. 1 egg mostly hatched and then I think the duckling died overnight. One egg has a duckling not progressing in past 24 hrs at all although I can see beak and duckling is quite the loud mouth- duckling even talks back to me, we've had some lovely conversations through the bator walls. Other eggs are slowly progressing or not seeming to progress much at all- and not peeping at all either. Humidity was 65% and I upped it to 75% last night as it seemed too low.
Any advice? Do my ducklings have a chance or are they pretty much all dead and don't know it? Anything else I can do?
Any knowledgable advice appreciated!
