Do coops need to be fully enclosed and dark?

New owner - 11 birds.

One of the #1 things I kept reading about when looking at buying or building a coop was ventilation. I was even going to convert part of our shed into a coop and was told I needed way more ventilation.

Problem I had (still have) is if I see all these "Commercially sold" coops like at TSC, my local feed store, even online - none seem to have much ventilation! They are all fully enclosed boxes with a small access door for the birds, maybe a couple small windows and maybe some venting along the ridgeline or soffits. Maybe on those last two, I have seen plenty that look pretty sealed up.

I also live in nice and toasty and rather humid South Carolina. Plenty of days with heat indexes over 100*. I assumed that more ventilation was better than less so I went all in on ventilation and airflow!

I need to take some photos but what I built is a hoop coop and it mainly just for protection. It is 4 x 8' for my 11 birds. It is wide open inside! Nothing is enclosed. I have 5 roosting bars along with a roosting ladder that they all use. I have a platform as well that is about 30" square in the rear. The top of it is covered about 3/4 of the way with a heavy duty tarp, the rest is open ventilation. The rear is also covered with the tarp. I have ventilation holes near the bottom of the coop on two sides for crossflow. Whole thing is covered in chicken wire (top) and hardware cloth (bottom) with a full sized door in the front.

Is this bad? Do they need that fully enclosed dark space? Do they need more coverage? The birds seem fine with it. They go in voluntarily at dark and I just shut the door (it is open all day). The coop sits inside our large run which is covered on all sides with fencing and has hawk netting over top. They free range in the run all day mostly hanging out in a small garden we have in there just for the birds and then go in and roost when the sun goes down. We have friends on a farm that have No coop at all. Their birds free range all over and they just have some covered nesting boxes along the outside wall of their stables. They have guardian dogs so the only predator is hawks to worry about there.

They were still hot in my coop and I had a box fan running to make more air flow when needed. I cant ventilate it more than it is! It keeps the majority of rain off unless we get a storm and it blows sideways into the coop. It is facing West so the East side is the back covered area.

If this is NOT bad - is this design OK for the winter? It will get cold and we can get snow/ice at times. I know egg production will go away unless we keep them warm and I may revisit that since we would like eggs year round but I didnt know if what I am doing is dangerous or bad for our birds.
 
Yep your design is good as long as they can keep out of wind and rain they'll be fine.
I have the same sort of setup, only smaller and I have my open end facing East as most of our storms come from the West.
I'm actually going to have a kennel (10x30x6) and it will also be an "open air coop" with the open end facing East.
 
Egg production depends on the day length not heat. Actually IIRC it depends on the night being shorter than the day or something like that.

I thought I read below a certain temp (40-45*?) that all their energy goes into staying warm and no longer producing eggs. If you can keep them warmer than those temps they lay, if not, no eggs!

I had thought about just adding on an extra tarp in the winter to cover a little more of the top and/or the sides to keep more wind out. What I didnt know is if I needed to actually wall off part of the coop to make it dark and fully enclosed.

Two of my roost bars are actually out in the open air part of the coop and fully exposed on all sides to air/weather. Several of my birds seem to prefer those spots and will rush in to claim them. Even if it rains they stay there! I have plenty of room in the covered part...

Mine laid eggs all winter with temps in the teens sometimes. I had much higher production during the winter months than this summer. That is why commercial laying houses keep 14 hours of daylight year round which is the same thing I did last winter and even now they get extra light in the mornings up to about 45 minutes a day now.

You can't believe everything you read on the internet.

Coops absolutely shouldn't be enclosed and dark. It's why a lot of folks who have those dark, shut up prefabs complain the chickens won't go in at night.

Cold and snow in most cases shouldn't be an issue as long as there's not a draft or moisture getting in. Obviously if you were in an arctic region, that would be different.
 
Back when I first got into chickens I was more concerned about keeping them warm in the winter. I have since learned that my birds have an easy time keeping warm, it's keeping cool that is a challenge for them. This is why I moving towards open air coop/pen. I raised 7 birds under a tarp covered pen last winter and it dropped into single digits several times (that's really cold for my area) and they just shrugged it off. Fast forward to summer where our humidity is so high fish could literally live on the banks and we get week after week in the upper 90s, the birds are now panting, drinking tons of water, and totally stressed.
You will learn far more from keeping chickens than you ever could from someone else that keeps chickens.
 
My coop is only covered on 3 sides, one long wall is hardware cloth. They still get hot because it's hot outside and it has vents all the way around at the top of the walls with good airflow.

As long as they're safe, dry and out of drafts I don't think chickens much care about their digs. We worry too much.

Ventilation is just as important in cold weather though to prevent frost bite. Since we add solid walls to the front in winter, the vents at the top of the walls prevent moisture build up. It also makes the coop darker, but the rest of the year there is bright daylight in the coop until nightfall. They lay just fine.
