There's no telling how long it will actually take. I've had eggs pip and finally hatch 24hrs or more later. Be patient and they'll come. Good luck and be sure to post baby picturesHi everyone, I am a first time runner duck owner...well soon to be duck owner. I have 10 eggs (6 runner, 2, cayuga, and 2 buff) in my incubator and a few have started to pip their shells. Just wondering what your experiences have been with how long it takes to completely hatch. Its almost the end of my 28th day & they seem to be taking their sweet time. Thanks for any advice/input. -Kyra
