Do I have enough ventilation?

[FirewifeJess]

I have been reading ventilation threads and think I have just barely enough at night, with sufficient, but not excellent, ventilation during the day. I could use some tips or reassurance that I won't hurt my birds the way things are, or a definite: you need more! Here's what I figured:
My coop is 35 square feet, or 5'x7'
During the night with the pop hole closed up, there is 3.26 square feet of ventilation (that can't be closed)
During the day with the pop hole open, there is 4.67 square feet of ventilation.

I have read that it is wise to have AT LEAST 1s/f of ventilation per 10 square feet of coop floor. I plan to have poop boards under roosting bars and scoop them frequently, so there won't be a ton of moisture in the deep litter. Also, I live in a VERY rainy part of WA state and we see way more rain than sun, so I also have to consider that any added ventilation has the potential of making things in the coop MORE humid. Thanks for the advice in advance!

Bumping with pictures...hoping for some help! I think it'll be alright but I'd hate to end up needing to stand in the rain while cutting a huge hole in the coop for a window in the middle of December

Looks pretty good to me. I like those kind of vents, and, I like that they are mounted up high. I'd say about right for winter ventilation. For the summer? Depends on how how your weather it. During heat waves, I find the birds won't want to be in the hen house, but out, in the shade, wallowing in the shade.

Thanks! Luckily for us, we don't have very hot weather often. I live in WA and it very rainy near us. Our yearly average temperature over the last 50 years is 51 degrees

You have more than enough ventilation for a coop in the NW. I have less in my coop, and I haven't had any problems in nearly 4 years. Even when it is very hot during the day around here, it still tends to cool off a lot overnight. The big thing here is keeping the rain out.
