So I have 2 duck eggs which have been in 9 days and 4 days.... And 6 more which have been in since yesterday... Duck Egg #3 - 9 days old - Is it normal to see the embro moving / stretching in the egg? I had the egg sat on the side, and candled it by holding a torch in one spot, no movement to the egg at all, and i swear i can see its eye moving around like it's stretching. Very weird lol Duck Egg #5 - 4 days old veins everywhere, growing fast, very happy. Duck Eggs #7-#12 - 3 are visibly fertile after one day in the incubator. This is my very first time of hatching any type of eggs, so its an amazing expierence for me.
