I so appreciate this post and am looking forward to more people weighing in. The coop is really what's keeping me from getting chickens as I just don't think I could really build something this complicated - and budget would be totally out of control because of the number of tools I'd have to buy to even consider it! I've looked at the pre-made and they're cute and marvelous but very expensive and the pre-cut kits don't look like they'd really be the kind of thing that could be insulated for Minnesota winters.
Maybe I should start looking for retired guys with tools....
Once you get the tools and build the coop, you'll not only have a coop for the same or less than you'd have paid, but the expertise to build or repair more things for yourself. Build your own! Win/win. Even if it comes out less than perfect, experience is priceless.
To answer mine:
1. A week. But the main building was already built. (old shed)
2. More expensive. By the cost of a roll of wire.
There are definitely advantages to having "junk" around!
I did put junk in quotes. It was junk laying there, but for sure useful stuff once I discovered I'd a use for it! I wouldn't mind someone with junk wheels around here, too. Sadly, in these days of pneumatic wheels, that's the first thing to go. What I would give for some of those old iron wheelbarrow wheels.
