So.....I have an African goose, and a Mallard drake, thats all the waterfowl I have. They have been mating for 2 years now....I have eaten 4 goose eggs this week and all were fertile.....So now she is setting on 3 of her own eggs along with some others....So in almost a month, If all goes well, I should have some Deese or Gucks haha
