Oh yeah, that link has a great discussion about stability and weight bearing in snow! Have you seen pics of our cattle panel guinea coop? I like them a lot! For the guinea run, I’m thinking snake resistant and no more nylon netting. I’m still thinking about it, but am leaning towards sinking 4x4 posts then using hardware cloth or 1/2x1 welded wire, with hardware cloth over the top. The hard part will be the supports for the top and dealing with the hilly terrain. That will make it painstaking as I’ll need to go panel by panel with the wire to accommodate the slope.
