I did not mean to sound short. The air flow is an important part of proper duck housing. You don't have to go huge, but from my New England with Runners point of view, what I want for housing is something that stays above freezing in winter, is pretty easy to get to even when there are 3 feet of snow outside, roomy enough for a watering station (see below), predator-proof, and not too hot in the summer (75ish ideal).
Those reduce stress on the ducks, and therefore, on myself.
Oops forgot the "below" part.
This is our watering station for ten ducks (Runners and a Buff)
