Good temp. To leave windows open?

[Jenjens]

What is a good temperature to start leaving the Windows open in the coop all night? I keep everything closed all winter so there aren't any drafts.

Thank you!

I normally start leaving the windows open when the nights are around 50°F.

I opened mine today. I usually don’t close them until it gets below zero consistently.

Really? Wow.

That is what I was thinking, but wanted to hear your opinions. So 50 is good all night? No issues that would cause runny noses, etc.?

One of mine is open full time until it gets below 0 unless it's really windy. If its colder than that, I close it because I don't want to risk a wind change over night. The other one isn't as sheltered, so sometimes I keep it closed. The more fresh air the better as long as there isn't a draft blowing on the birds. If you are trapping heat, you are trapping humidity.

Cold air doesn't cause runny noses.

If I waited for air temps to be consistently over 50, I wouldn't be able to leave them open until July.

Cold air doesn’t cause runny noses.
My wind tends to come from the west or southwest, my coop is blocked on this side and the windows aren’t on the side where the wind direction comes from.

If the windows don't blow directly on the roosts I'd never close them at all.

Chickens have built-in down coats and need good ventilation as much as they need good food for good health.

There's no hard number for temps and open windows.
Much can depend on your particular site and also the coop configuration.
