What is the difference between "ventilated" versus "drafty"?

Thanks Vivienne, good information.
I have a leghorn banty that I worry about in terms of frostbite & comfort...

That is how my Coop works, (see my BYC page for pics) I have a angled roof with ventilation year round under the eaves on the low and high sides. The windows get closed for the winter and stay open for the summer. The sub-ground level deep litter composting pit helps maintain steady tempertures during the winter. This has been working for a couple decades now.

I hope to retire to North Carolina one day and occasionally they get snow. What is a sub-ground level deep litter composting pit?
