Have 9 chickens who need proper space. Looking for information

This depends on your climate. If you have cold winters you'll want a taller coop so you can place the vents far above the roosts. This allows the warm, moist, ammonia-filled air to escape but not let cold drafts hit the chickens.

I'm in the south. Will get a snow here or there, and about 3 months of cold.

Make the coop at least 6 inches higher than the tallest person who has to go in there if possible. That way no one bangs their head

I am considering going coopless for now. Just a partially covered run. In the covered area, have nesting boxes up with several roosting bars.

Then add a coop toward winter time.

Move them to new grass areas one a week. So now I need to find a build for this size that's movable.

Any suggestions?

How about something like this?

Lots of interesting opinions here! For the record in the 70s I inherited my grandfather's original RIR flock started in 1940. In the 90s some scum STOLE them. It took me about 10 years to recover from the loss before I finally started again. That time I had Buff Rocks. They were all killed by a pack of coyotes and feral dogs. In 2008 I started again with chicks from Meyers and Cackle. Now everything I've got is home-bred and the coops and runs are literally outside my back door. Now I have security lights.

The coops all have 4 sq ft and 1 linear foot of roost space per bird. My runs are 1/2" hardware cloth with shade cloth over the roof. Since I won't risk free ranging ever again, I have 25-35 sq ft of space per bird in my runs. RIRs are loud, active breeds. They all get along very well IF they have enough space. They prefer being outside in all weather except freezing rain.

Hopefully something here will be helpful.
