Hi Everyone. I'm new to BYC and I need some help with a project. I inherited the dog pen shown below from the previous property owner and I would like to turn it into a chicken coop. The pen is 16' square and is very well built. My plan is to fence in a 1/2 acre surrounding the pen for daily run area with lots of dirt for bathing and junipers to keep the hawks out. They would then be locked down at night in the pen/coop as coyotes are an issue. Basically, I want to build a structure within the pen that I could use as a coop without doing anything to the pen itself. We live in an arid high desert climate in southern Oregon and the box wire lower half will provide plenty of ventilation. I am going to have the floor poured with concrete, it is gravel now. I have good wood working skills and tools but am not a carpenter by any stretch. Any help would be greatly appreciated.
