I found a small green egg on the front of a boat at a pond up the road. I put it in the incubator and theres a pretty large embryo inside. Its about the size of a game chicken egg. So its small for a duck egg. Its a very light green. It also has like a white spot around it. I don't really think its a mallard egg do to the size. So what type of wild duck could of layed this?
