3 boxes may come in seperate shipments. However, this is HUGE when set up and it's very very nice. I added 2 gates in the middle to section it off into 3 sections for my different breeds. Each section will hold 8 - 12 chickens each very nicely! Comes with everything to assemble. Use the holes in the bottom of the legs to place a stake in and level everything out for ya. Use the green wire to wrap around the pole while weaving it through the chicken wire. I did this on every pole, working from one side to the other so as to tighten up the chicken wire. PERFECT for us! Would seriously be able to park a car or truck inside. Would make a great frame for a large diy shed if you wanted to enclose it.
