Sunday was the day of lock down for the duck eggs. I decided to put some paper towels in the bottom for traction and to make it easier to clean after they hatched. When I moved 2 of them to put the towels in there,I noticed they had pipped. After I put the towels where they had been,I moved them back to where they were. I don't them I turned them in the process but the fact I moved them I thought maybe I disoriented them. The next morning I noticed another egg had pipped and a while later it hatched. The 2 that had already pipped still haven't hatched yet or changed at all that I can tell and it's been 48 hours. They're not actually suppose to hatch until tomorrow but the fact they've been pipped for 48 hours and I don't see any changes I'm getting really concerned. Any suggestions on what I should do?? Should I go ahead and carefully open them up the rest of the way or just leave them alone until Thursday?
