Frosty Windows

[Gammond]

It was -10 last night. We have a school bus chicken coop; I have the windows opened about 1/4 the way... I noticed frost on the windows this morning - it's a sunny morning. Is this normal? Should I be worried?

-10 C not F

if the frost is on the outside of the windows no worries
if frost is on the inside, you need more ventalation

At -10 I think some frost on the inside of a window would be inevitable. I believe some people get a bit carried away when they start talking ventilation and how many sq/ft of ventilation you need per bird. We get so much blowing snow in my area that my coop would have snow inside it if I had the "recommended" ventilation square footage or the coop would need to be in a building.

I corrected my post... it's -10 C.. but still, I'm even getting frost in the sectioned-off 'storage' part of the bus near the front. There are no birds in this area. Here's a pic of one window in the coop:

I'm getting some frost near the roof seams as well:

Fall and spring are always damp. Frost on windows in unoccupied areas would tell me the outside humidity levels are probably high and there are some temp swings between days and nights.

I've got a cheap/small temp & humidity gauge in my coop. The inside coop humidity is always what the outside humidity is. Makes sense since there's vent holes. I think the biggest issue is excessive humidity. Once winter sets in and the outside humidity drops, my coop's humidity follows suit.

What about the front and back windows that aren't open, are they also frosted on the inside?
Also, school bus coop sounds awesome!

This makes a lot of sense - thanks! The snow hasn't 'stuck' yet and keeps melting.. Humidity is quite high right now.

All of the windows are frosted - even the large front windows that are blocked off from the chickens.

Same here.
