I have 2 sets of eggs waiting on some babies. When do you give up? Neither set show signs of anything. Duck eggs were set on 3/10 and Chickens on 3/16, these were both done in incubator. I also have a mallard hen that started sitting on a nest in pen as well around the same time. In the pen we have 3 mallard hens and 1 drake and a pair of East Indies. Several nests and they are sitting (not sure if EI has a nest or not since they keeping them covered when not sitting. Should they be seperated from one another once they hatch, any suggestions. Lots of questions, but we want some babies soon!
