In looking at the CC-28, especially the one picture with the girl standing next to it... I wouldn't put more than 2 full sized hens in there. The CC-03 is not much bigger. The coop builder/supplier states "Will Hold up to 4 Hens or 6 Bantams"
( Very depends on breeds please see coop floor plan dimensions and make your own decisions ). Of course you can cram a few hens in either of these, but I wouldn't.
Neither of these coops has enough ventilation!
I thought I had plenty of room for my 4 hens with a 3x6 coop and 7x6 run. This winter the feather plucking started because they didn't have room to get away from each other.
Also - you're in the Pacific NW. A lot of rain. Fact of climate. I understand most of these pre-fab coops are made overseas in China (nothing against that). My concern is more that the lack of quality of the wood they are built with. Their site says they're built with "treated fir timber". Treated with what?
When you go to Lowe"s Home improvement website to look at buying treated lumber, the first step you take is determining what part of the country you're in. Different treated lumber for different climates. You're looking at investing hundreds of dollars on one of these coops that i'm afraid wouldn't last more than a few years. Your chickens will outlive the coop.
Check out your local Craigslist. I found this guy in Seattle thru Craigslist who makes coops.
www.chickengardener.com (no I don't know him, but I did check out his website). I think you'll be much happier going this route if you aren't able to build it yourself.
