The math would work if my posts were straight. The posts didn't set straight, which is 90% of my problem. They are at a slight angle (there should be 7' 5" between the posts, 8' on the outside, top and bottom. They are only the correct distance apart at ground level.) But I was in a rush and wasn't able to keep the posts upright while the concrete set. NOTHING IS SQUARE!
Even the ground slopes, which is why I didn't cut my posts to length before setting them. I'm also working only with a jigsaw and a hack saw - I have NO idea how I'm going to do the roof (I have plastic corrugated roofing, but attaching it is... a whole other ball of wax.)
Your chickens are not going to care much if things are a bit out of square. They need it to be as safe as it can be against predators and to provide a healthy environment. They will be okay with "unique." No one will care, really.
We didn't cut our posts before we set them either because of our ground slope. After they were in we marked a level line and cut off the tops with a circular saw. There were thirteen posts---fun times.
This will be fine. Just keep going, one foot in front of the other, and it will get done.
I do like the blue!
About that roof---here's a video. (YouTube can be your friend.)
