Rule of thumb have heard is 1sqft of vent per bird,
but that can be impossible depending on size of coop.
And different climates have different ventilation needs.
How many birds do you plan on keeping in there?
You're going to have a ridge vent, per se, at the peak?
Do you have a layout of where nests, roosts, feed/water will go?
Will it be all coop, or part run too?
Problems I see with A-frames are:
-Tight head room both for keeper and birds,
hard to do your stack up of vents above roosts above nests.
Roosts can end up so high there's no head room for getting up to roosts.
-Slanted 'walls' don't shed weather well. There's no real 'roof' to help protect vents and windows, you basically have to have a solid 'walls' all the way to the ground.
Might be especially difficult in deep snow areas.
Go with large (2-3') 'roof' overhangs on both ends.
Place coop where it is protected from winds,
where prevailing winds hit side rather than end.
Just my thoughts.
