The sugar solution in hummer feeders does not  freeze until about 20*F (-3*C).    Consult a high school chemistry book for an explanation.   
I have two feeders near each other.  If I think it will get cold enough at night to freeze the sugar solution, I will bring one feeder in for the night and leave the other one out.  If the outdoor feeder freezes, l'll swap the two until the frozen solution melts.      Bill Anderson; Edmonds, WA.
