Anas platyrhynchos nest with eggs

Last week my grandfather founded Mallard nest with 12 eggs in it. We managed to take pictures ot it ,but didn't want to disturb the bird so we just took 2 pictures of the nest and walk away from the nest. The nest itself was made near a bush and was very well hidden. Other interesting thing is that it was about 20m away from the water. Here are the pictures :)
