Should I end the development of the egg in my incubator that appears to be developing two embryos? They're on Day 11 right now, and both embryos very active. My husband made a joke about "playing God" by letting them incubate, but I didn't realize the egg was a double when I put it in there--I just knew it was larger than the others. Well, longer, anyway. I know from reading here that when there are two chicks in one egg, they almost always both die. Is it more humane to just kill them now, or would you let them keep developing until they quit?
