I am on day 27 with 3 duck eggs in the incubator my one piped on day 26 but not all the way through and has not done any more pip but is still moving I did not move the egg but I put a flash light on it to see if there was still movement. I woke up this morning and the other two eggs are pipped one more the the other! Should I be worried? Here are some pictures and videos attached in order 1-3 eggs
