I have a rooster,(a "hybrid") and a female astrolop, (not sure about spelling), that he loves to make sexy-time with. whats getting me is that she never sits on her eggs for long, does this mean that he is sterile? If hes not can I incubate the eggs? Can you tell if an egg is fertile without breaking it? Will a super hybrid have something wrong with it, or just look weird? Can you eat fertile eggs without getting sick?
