I've read a number of threads on this, but nothing quite answers my question. I had two duck eggs internally pip Sunday morning, which was day 25. I waited until Monday afternoon and neither had made an external pip. One of them stopped moving or making any noise. At that point I made a small external pip on both. Tuesday morning the one still wasn't moving. I openned it up and as I was sure, it was a dead fully developed duckling. The second stopped moving this afternoon. I'm afraid it's dead too. Any ideas of what's going on? Should I be helping them?
