Dutch bantams and cold weather

[columbiacritter]

We are headed toward about 5 days of lows in the teens and single digits. My big girls I'm not worried about, their coop is warm and dry, but my dutch boys in the bachelor quarters is different.

Their coop is draft free but not heated. I'm thinking for bringing them into the basement for the duration of the really cold weather.

Any dutch banty people out there to tell me how much cold they can be happy in?

I am also going to be in weather in the low teens for the next little bit. I have bantams and standards + two teens(fully feathered for long time). I have good secure coops that are draft and rain free. They do fine, even last winter when we had snow for three or four days-a record here-

I would think that they would be fine.
