I want to convert a piece of furniture into my coop for 2-3 bantams. The furniture is 71" tall x 35.5" wide x 18.5" deep. I'm going to keep the coop in my garage, and there will be an exit ramp to a doorway in the side of the garage, to a large outside covered run. I'll be attaching their next box to the outside of it. I'm sure the height is okay, but is the width/depth?
