Its starting to cool down here in Tennessee and its cooling rather quickly. Last week I was having to worry about my ducks overheating now I have to worry about them freezing. Last night it got down to 50 degrees (Fahrenheit). I just put in fresh straw and they have some little boxes in the yard that they can go into during the day. It doesn't usually get absolutely freezing cold but it can dip below freezing a time or two. What all can I do to help my children stay warm?
