That is so sad...Get it covered. I lost my first peahen because she decided to make her nest out in the open. I found her apparently drowned after a night of thunderstorms with torrential downpours. She was still on the nest and the eggs were still safe under her, but they were almost submerged in water and she was just dead, no injuries I could find. That was when I quit letting hens decide where to nest.
