I am thinking of making PVC hoop coops at the new place. My plan is to use 10' sticks of 1" PVC connected together. That way, the bends will be gradual. I want it to be 6' at the peak, at least. That way I can walk inside. So, overall, each piece will be 20' long plus an inch or two added by the connectors. It may end up being more than 6' at the peak, depending on the final width.
