My duck, Peeps, apparently really wants to protect those eggs from the predator (me) that takes them from her everyday. She has a big nest of straw in one corner of the duck house. She covered the eggs with the container I put their oyster shell in (after she moved it 4 feet from across the duck house) then covered that with about 2 inches of straw. I found them anyway....sorry, Peeps! I am feeling guilty for taking them from her! Particularly this morning.
