Where is Mama?

Just to update you. We have not, unfortunately, seen sight nor feather of Mama Duck for about 10 days. We even put out some food in the hope that this might lure her back but to no avail as all we saw was a Wood Pigeon having a good feast! We are away over Easter and hope to have some news when we return although we are beginning to wonder if this is not 'our year'..................
