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?
