See the "Cold Coop" link in my .sig below for a much longer discussion of the subject.
Readers Digest version: in your climate you would probably not need a heat lamp for sensibly-chosen breeds, but because high humidity (due to weather) is a concern it would be nice to have the ability to turn on a lamp if problems should develop. An extension cord, intelligently used, would be at least a viable emergency measure; in the long run it would be nice to have electricity run to the coop for lights anyhow.
Good luck, have fun,
Pat
