My PCV chicken tractor I posted before didn't mind the wind. It's light enough to pull around by dragging. It didn't budge in winds because I think it's low enough that the wind can't get under it. I have the closed off end to the north and your looking at the west end. Unless it's a hurricane, wind isn't blowing from the southeast often which would lift it. Although I do remember a few years ago a sudden burst of wind from the south took a few calf hutches for a tumble including the 500 pound 'group hutch'. This tractor worked great, but like I mentioned it was tough fastening nests. I don't have any roosts although I have a brace in the middle about a foot high that they didn't use. I have the pieces to make another one including the 45 degree wye and a 4-way Tee which is used at the top to connect the legs at the middle. A 3-day 90' elbow is needed for the top at the end legs. I think it cost around $200 per tractor which isn't cheap. The pieces mentioned can't be found at many hardware stores in 1 inch, I had to order them online.
