Well, my mama buff was sitting on 17 eggs. But then today I noticed she only had 16. I look all around for the egg and find it in her pool. It was bad and had exploded. Is there any way that she had picked up from the past ( she has had an egg explode in the nest) and taken the egg away from her nest to the pool? How could it have gotten in there? Did she carry it out?! She is a petite duck, weighing maybe a couple pounds ( not good at math ) but is only half the size of her mallard mate.
