anchor system for coop on skids?

[ziggywiggy1]

I’m in the process of finishing up my first coop build but ran into a snag with the recent storms that passed through. The wind knocked the coop off it’s block foundation, luckily the structure appears all in tact the only damage was the ends of the roof that extended beyond the rafters. I knew this could be a potential problem and I’m glad this was the first test and not a hurricane with chickies inside. So does anyone have a good anchoring system they’ve used for these movable coops?

Pics would help here.

Without seeing what you’re talking about - ground anchors.
Heavy objects tethered to structure (concrete blocks, filled buckets, etc), or stakes into the ground would be simple (stakes, corkscrew stakes, t post, rebar, etc)

ignore the off kilterness, we just didn’t have 3 people to get it back on its blocks correctly so we’ll fix that soon

Wow that's crazy that structure caught enough wind to shift and fall over; I'd imagine it would have been heavy enough to stay planted, but perhaps it was just some crazy wind you got....but would likely happen again if you don't remedy it

Looks like it fell on its back, right? I'd guess it happened because of the amount of roof overhang on the high-side, the roof's pitch, the very skinny footprint vs height vs roof size, lack of wind breaks in your pasture, etc - all contributed to this event

I know before you said in your build thread you don't want to have any concrete foundations on this project. IMO setting 4 corners in concrete isn't very intrusive and easily removable in the future. Heck, even a few of those solid-cast concrete piers are likely better than hollow cinder block - significantly more weight and have anchor straps to fasten the structure to them. Another alternative is to drive some U-Channel/sign-post into the ground at each corner and lag bolt the structure to those stakes.

If you were considering slight design changes to lessen the amount of air lift underneath the roof, my gut says add more ventilation space underneath that low-side so there's more "flow" through the structure so less wind catches under the roof. Adding that air gap would also make the roof less pitched and less sail-like, which should help in multiple ways.

Bummer on that nice new roof taking a beating though, stuff happens.
