I've already got an old rabbit hutch I converted and a kit house someone put together and then changed their mind about getting chickens. I've got 12 hens and would like to add maybe 12 more. I've seen a Giant Deluxe Coop from Cumfy Pets and have a chance to get one for about $400. Are these any good? I realize I could probably get the materials cheaper and build something, but this is not a talent and the time and tool factor are limited. Any thoughts, positive or negative are very welcome ... Thanks in advance.
