Okay. Here is the question: Can I tell if a goose egg is fertile the same way I tell chickens and turkeys? Here is my story: I have had a pair of white Chinese swan geese since last spring. They were about a week old when we got them. As they developed, one seemed obviously female and one male based on behavior, and as they continued to develop, the "gander" developed a bigger, brighter knob and continued to act protective and dominant. My girls even showed both geese in 4H last summer. The"gander" did very well; in fact, the judge said if he had been a bit older, he would have one the whole show because he was such a good example of a MALE Chinese swan goose. The female developed a pouch and has been laying off and on since last fall. Last fall, I checked a few eggs, they looked infertile to me (based on my experience with chicken eggs). This spring I have cracked a few, and I definitely saw the bull's eye. So I thought we were set to let them hatch out babies. They have a nest of about 10 eggs right now. HOWEVER, yesterday I went out, and the "male" was on the nest, and when I looked close, there was an egg that was wet and had obviously just come out of "him", Not a gander -- but now I am completely confused, since I thought my eggs were fertile -- help! Now, there is a pond across the street, and we see wild geese all the time. Is it possible they could fertiilze them? We are so disappointed because we thought we had a pair.
