So, I took the eggs from my first time broody mama duck after she incubated them for about 3 weeks. She was getting off the nest for longer than I felt comfortable with and rolled three eggs with babies out of the nest and cracked them open. I replaced them in the nest with unfertalized eggs and mama is still setting. The eggs have now started to pip in the bator and I am not sure what I should do to get them back to their mama. I am concerned that because ducklings imprint so strongly that slipping them under mama after they hatch might not work. Should I move the eggs back now that they are pipping or wait for them to hatch and then put them under her at night? Has anyone had success or complications with this? I have posted a couple times before so I am sorry to keep asking the same questions but I still haven't got any answers and I am hope that SOMEBODY can help me
