Anyone using greenhouse vent openers on their coop?

[Eggstatic ChickyDoo]

I'm adding windows to the south side of my coop to lighten it up inside/give the hens more options for winter sunbathing on blustery days. We're far enough south (northern Virginia) that the coop does heat up quickly in the summer, so I'd like to put the windows on hinges and prop them open in the summer, but I was looking at automatic greenhouse vent openers and they look like they might be an even better solution, especially for spring and fall.
Anyone have experience with them or something similar? What brand/type? What do you like/dislike?

Not really an appropriate application for a coop.
Once the weather gets to that point, the more open ventilation the better.

I agree - I'm in Vermont and I keep my windows wide open all day and night from about late-spring to mid-fall. Then I close up some and keep some that are far from the roost partially open throughout the winter. Do you have ventilation above their roost?

Can you please explain a little more about why not? We regularly have spells of 70-80F weather (lows in the 40-50F range) alternating with spells of highs in the 40s and lows in the 30s. I see vent lifts advertising that you can adjust them to start opening 60-85F, I thought this could allow the windows to open on those warmer spring and fall days to offset the extra solar gain the coop will be getting.

Ventilation for the coop is: under the rafters is open on the north and south sides (4"x36'), 2'x3' triangles on the east and west sides at the ridgeline, and a 2'x5.5' doorway (no door) into the covered part of the run on the west.

On the lower portion of the south wall I added a 2'x3' window late last winter, which I covered and propped open full time from mid-May until mid-September and on warm days March through October. The new windows are higher up, so opening and closing the windows on a daily basis would be inconvenient, though I do plan to climb up at least once in the spring to attach an opaque covering to the panes in the spring and open the window and in the fall to remove the cover and close the window.

There's just no need to control the window openings like that.

Well maybe for these high up windows.
How high are they?
I leave my 12' high windows open once we start getting into 70's - 80's.

I leave all vents open all year.I open a big window in the summer months so they have a breeze. Covering the vents with a filter allows the chickens to get fresh air when its windy.
