also with the snow melt the pool was completely full it should have been easy to fly out.... I've watched them fly over 100 yards (six inches of the ground)...that's what I figure too cuz the only way she got in there was to fly in...... Why didn't she fly out..... And if she would have just floated I would have found her and got her out..... It's odd to say a three year old duck drowned. I've been fortunate not to lose any since the neighbor dog incident almost three years ago. If course I had that close call last fall with my dogs.... But i know that if your gonna raise birds eventually you will lose some. I've been fortunate. I haven't even lost any ducklings or chicks.... I still feel like I let her down.... I always do
