Here is the coop my 2012 peas are inside of. Originally built for chickens,it now is going to be a new building for growing out newly hatched peas next year. I only have doors on 3 of the coops,I can during the summertime swing open the plywood doors and I have a piece of welded 1/2"x1" wire to keep birds inside but allow air movement especially when it gets 95 degrees outside here in July abd August. The white sided building you can see above the coop roof is our garage,and between these I have pens built to keep birds seperated.
