New Chicken coop

[Alex S]

You're going to want more than that to shelter vents at the gable peaks. The roof-peak ventilation is the most critical because heat and ammonia both rise. Ammonia is lighter than air and the rising warm air carries the moisture away to keep the coop dry.

Why not just put a vent under the drip edge? It lets air in and out, plus its shielded by rain

not all rain and snow falls perfectly vertical

True, but then there are vents like this

Or if I just cut a hole and put hardware cloth I could put a slanted drip edge over it. seems a lot easier then building a cupola or monitor.

My lumber yard has 10-foot boards

Depends on the lumber yard......doubt they'd be found in a big box store.

True, that's why I decided to just buy 2x4x12s so I can get 1+ feet of overhang on the sides. Then just do a drip edge on the front and back, which gives me 1-3 inches of overhang

(Sorry for the sloppy writing. its hard to draw w/ a mouse)

You've got these terms mixed up.
Drip edge goes on the eaves, fly rafters go on the gable(to extend overhang there)

let’s say that vent was 1ft by 1ft.

instead of now having 1 sqft of ventilation, you have way less because most of
it is blocked.

Referring back to my first post: https://www.backyardchickens.com/threads/new-chicken-coop.1505595/post-25237393

You want 10 chickens. That means that you should have 10 square feet of permanent, 24/7/365 ventilation which is best located above the chickens' heads when they're sitting on the roost.

One of the easiest means of achieving this is to leave all or most of the gable triangle open, covered only in wire, under a generous roof overhang to keep blowing rain out.

Those little louvered vents give square inches where you need square feet.

Chickens have very delicate respiratory systems so they need BIG air for optimum health.

Because you need square feet of ventilation, and that provides square inches...

Not opposed to those, but have yet to meet a shed with room for enough of those to meet the ventilation needs of chickens - and ultimately its both cheaper and more effective to let your rafters overhang the walls, install hardware cloth under the eaves, and let the building breathe along those long, weather protected, gaps. Also, easier for you to construct than more traditional, house-like, methods.

i have a 2ft overhang, but because of the pitch of my roof i was still concerned with rain blowing in, so i mounted this fascia board in front of my ventilation. i still get the benefit of fully open vents, but my coop is protected from high winds and sideways rain.

So where the black lines are, that should be the fly rafters, and the purple highlight should be opened up for venalation? Or just overhang on all sides?
