Ventilation/Vents Placement

[3KillerBs]

hmmm I has planning on putting down some plywood then metal panels on top wonder if that would be overkill. I live where it snows so wanted to have some layers of insulation to protect from the elements

In some places that's unnecessary and in some places it's a good idea.

We installed our metal on purlins, which is the usual practice in our climate. But in some places that are cold and humid you can get condensation forming on the underside of the roof and dripping into the coop.

Try to find out what local metal roof suppliers recommend for farm buildings/livestock shelters. They'll know your local conditions.

I know I've been asking you a million questions but I got one more for you. I'm making the coop with a slant roof like a shed with one side only being roughly 3/4 feet tall from the floor of the coop. The coop is raised 2ft then has a sheet of plywood(like a table) then 3 feet on one side and five feet on the other. If I use an elevated roof with overhangs would I run the risk of having the lower side create a draught and blowing on the chickens? the roosting bars will be on the taller side. the coop is 4x8

Our barn in NH was built with purlins, then a layer of that bubble-wrap-looking insulation under the metal roof.

My sister’s run-in shed (for her horses) has a metal roof on purlins, no insulation, and I have noticed occasional minor condensation drips in the attached feed room. I assume that has to be from temperature changes acting on trapped interior air, as there is nothing in the space that would create moisture (such as a breathing animal).

Ventilation should be at least a foot above the height of the roost. If the roosts are a foot below the lowest level of the roof they'll be fine. If you can't put them that way, you might want to consider raising the roof to allow it.

There are ways to make a draft baffle on the inside of a coop to deflect air away from the roost but I'm not familiar with them because of my climate. Some people in cold climates put furnace filter in their vents in the winter to block wind.

A key thing with insulation is to make sure that the chickens have no access to it because they will peck it (and if it's the styrofoam board they'll eat it).

Better to go a foot above the heads of the birds on the roost....so more like 2-3' above roost.

I defer to your superior knowledge of cold climate needs.

You mean a foot above their heads, right?

Yes, fixed it, thanks, now fix the quote?

No over kill, it's best to have wood between the birds and metal. Condensation is scary in the winter months.

It's a work in progress. We are trying to decide which would be safer. A secondary fencing of Hardware Cloth 1/4" or an electric fence. We have a boat load of predators. So, that is something we'll get up prior to putting them out there full time.

Thanks!

Go with 1/4“hardware cloth.
