Last year we had a family of seven swans on cree lake Kendallville indiana.In the fall when the five babies lurned to fly they all took off.This week I think it was the 10th of march I went out in front and setting out on the snow on the ice was 3 swans. When my wife came home from work about an hour later they were gone. Yesterday I saw 2 flying around over the lake.I was hoping they will be all right this morning it was around 2 below tomorrow it will be in the 40's. What do you think?
