They look great. With ko shamo proportions are important. 1/3 of height should be legs, 1/3 body and 1/3 neck and head.
Have they got split wings? Also from the back they should have the "5 hills"

To be honest with you I don't know. Most chicken breeds don't really care if it's cold. I live in the UK so I don't get much frost, the coldest it gets is maybe -5C?
I don't give my chickens any heat.
My great grandmother used to keep chicanes in a shed in Poland and she never gave them any heating. Let's be honest people kept chickens for centuries in wooden sheds and never thought of giving them heating.
BUT ko shamo show are special... and they don't have much feathers, so I'm not sure...
