I checked with the company some time ago and was sent this note. The full sized 4x6 coop is $4000. This is to house 16 chickens, which seems a little cramped to me.
The half sized coop for 9 hens is $3000, and the smallest coop is $2000 for 2-3 hens. I suppose if you're keeping banties this might be fine size-wise.
Granted, the coops are made with nice lumber, not the cheaper grade woods. Nice glass windows and the coops seem to be well thought out in design.
Plus, the shipping to my place (they are up in northern California, I'm down in the southern area) would be $400 -$700. The coop is shipped complete.
Little too rich for my blood....
