Hi, there is a small pond behind me where 2 swans live,.. I can see them sitting on the ice, curled up.. Are they ok? It's really cold. I did go over and throw some bread and corn kernel mix I had bought as bird food, There is a fence are puns the pond, and the snow banks are high. Is the weather ok for them. I will go look and see if there is a break in the ice for them... I couldn't tell earlier. Thank you.
