It is very understandable that you did not want to use that egg.I had Toulouse geese for a year and a half, several years ago. I got them as adults, 2 pairs, and they did NOT love me. At all. I let one goose hatch some eggs, and suddenly I had, I think, 8 geese! Dang... The next winter, I had goose eggs so huge they went from the base of my palm to the tips of my fingers, and I don't have teeny dainty hands! And I had an egg every day from Valentines to Father's Day. One day, in a puddle in their pen, was a shell-less egg. Perfect in every way in shape and heft, but no shell at all. I remember being REALLY reluctant to pick it up for fear of breaking it all over my hands, but I got it up and dumped it safely. Wasn't going to try to eat it after being in that puddle for a while.
What did you do with the geese?
