If you are still looking at kits, heres an idea.
Its called the Easy - Up. I have used several of these kits over the years and am totally pleased.
What you get in the kit is corner braces, foot pieces & screws/washers. You have to buy 2x2's to make the actual shed/coop.
They give all info. to set up on the boxes. No cutting angles at all.
Not expensive in the end, fast to put up and holds under snow. You can brace in the center..it is made for that.
I have lots of heavy snow in winter and some sheds are now 9 yrs. up.
You can just use plastic/tarp to close in (over wire) or O.S.B. board, depending on what you want to use them for.
Use part of a kit to make a smaller unit or the whole kit will make an 8 x 8 x 6.5 ft one. Or as I have done 9 yrs ago, joined onto the one kit to make a 8' x16 ' long grnhse.
There is a web site but I got mine at a building supply store.
Hope that helps.
