No idea what type duck. This gentleman at my work that buys chicken eggs from me, left it on my SOs desk witha note" Found in Yayuns front yard-please help save baby duck egg" lol. I dont have any other ducks but am relying on the help of my BYC friend who has them to help me out. She has also offered to take it if it hatches if I dont become to attached. The egg is cream in color....although can appear almost green ish. Duck eggs are so hard to describe color!
