Ventilation question

[SammyJo425]

So my plan for my coop ventilation will be permanent 18 inches above the roost bar. On the two sides and back of the coop. I want to put in two pop windows below the permanent ventilation, for added cross breeze in the summer. I live in NY we have cold winters and hot summers. So the ability to adjust the ventilation is def something I want to be able to do. How far above the Roost bar should the pop windows be?

I’m also attaching it to my already existing greenhouse so that’s why you see the clear corrugated roofing above one of the pics. Their coop with have a roof and covered run

If the bottom of the window is a foot above the roost it should be good. They settle their bodies down on the roost when sleeping.

You feel that the permanent ventilation is insufficient? Dunno where the 18" measurement comes from, but that gap from the top of the walls to where the roof will be, looks like plenty of ventilation to me if it's on three sides.

I read that the ventilation should sit at least 18” above the roost bar. I have room to extend the height of my roof if I need to. I also read that in the summer, the more ventilation the better. So I would prefer to have a few windows I can close in the winter and open in the summer so my chickens aren’t suffering in the heat

Thank you, that answers my question

Yes, this is good thinking.

People in areas with cold winters and hot summers need to make their coops flexible to cope with varying conditions.

A little gentle breeze across the roost in hot weather isn't a bad thing. What's to avoid is a breeze strong enough to ruffle the birds' feathers when they're on their roost.

Extra height in the coop is a good thing. It gives hot air somewhere to go, allows you to stand up (very helpful, just ask your back and the top of your head), and makes more room for ventilation.

Here in Michigan, we can get pretty cold too. I put furnace filter material over the bottom 6-8" of my big ventilation openings to cut down on the breeze that can blow through. I also put it over the areas that are around roost level, to cut out the wind. There is still air exchange, but no draft on the birds.

In mid-winter, the temp and humidity level in the coop is about the same as it is outside. That's how I know I'm not trapping moisture in there.

If you can put in top hinged windows, they can act as their own awning to stop wind and precipitation from coming in.

As I have such good reason to know: https://www.backyardchickens.com/threads/another-reason-to-build-a-full-height-coop-run.1484191/

Sounds like a good plan.
Don't forget large roof overhangs with fascia to help block the winter winds.
