I have a chinese knobhead gander and a white emden goose. We got them as babies last year and this morning we found her first egg. We candled it this afternoon and didnt see anything. Will she be able to hatch this in these cold temperatures? How do we know if these eggs are fertile or will become fertile? What happens next if or when it becomes fertile? I just need any information that anyone can help me with in this very new experience.
