If anyone has had ANY experience hatching twins PLEASE SHARE! I have twins ducklings in the incubator and it is hatching time. Everyone else in the incubator has either internally or externally pipped, but the twins show no signs of progressing into hatch mode. I do not want to let them be to die in the egg, nor do I want to intervene too early and cause them to die. I DON'T KNOW WHAT TO DO!!!!!!!!!!
