I use fence panels for all kinds of things and will probably do something similar to this in the future. Did you use the panel with the graduated spacing? I couldn't tell for sure from the pictures. I get the impression that this is not fastened down and that you can scoot it around like a chicken tractor in the mild seasons. I think it is a reasonable way to add shelter for more birds/different birds. It is also a simpler build than a framed, wooden coop. I wonder, like another reviewer, if that is enough ventilation in the winter,. I am in the deep south and that plastic would give me condensation issues. I would also have to tie it down or stake it.
