How the heck do I know if an egg is carrying an embryo or not? My boyfriend and I went on a hike and scavenged for edibles and I found d so.e eggs but when I went to cook them there was an embryo hawk or owl in there. The rest of the eggs were fine a M d just had a fertilized white dot on the yolks, but the embryo really grossed him out. Is there a way to check so I can keep this from happen to ng again? He seems very upset. The rest of t h.c e eggs were delicious though
