I'm new to chickens, and haven't actually ever owned any, so I wasn't sure what size coop to get (for 5 chickens) I ordered a 8x8 shed from Home Depot after reading a lot of people recommend that larger is better. I'm not really good at building things so I decided it was worth it to just get a shed. It has a 12"x12" wall vent and an 8 ft ridge vent. There will be two 2'x2' windows on two walls (so 4 windows total) that can open.
I was thinking of using one window as a pop door. Plus I could use the windows for added ventilation if needed. My questions:
1. How high should I place the windows so they can be used as ventilation, while still having space to make one into a pop door? (not sure how much space most pop doors need to function)
2. Should I have a poop board?

I will post a picture when it gets delivered! I also updated my profile with my location. I live in Reno NV. It gets pretty cold in the winter and snows a little, and has a super dry climate. In the summer it gets really hot, sometimes over 100, but it's dry heat. I'm not sure how much ventilation I need since my climate is really dry and windy. I don't want them to get to chilled in the winter.
My automatic pop door opener can accommodate 10.5" x 13" . I'm sure the engineers designed it to fit most chicken needs. Here is a quick link if you wanted to read some of their specifications.
