1. What did you do?
Built a half-high run on the original version of the Little Monitor Coop. We were trying to save the cost of another roll of hardware cloth.
2. What were the consequences?
Cleaning was a nightmare and collecting run eggs or anything else that needed access under the coop required sending a child in with a hoe.
3. Did you fix it? How?
It could not be fixed under those circumstances. We just had to live with it.
4. What did you learn?
Nothing, apparently.

I accepted the gift of another half-high structure this spring, turned it into a brooder and had
this happen last month.
More seriously, build your coop and run considering your ability to access every nook and cranny. Hardware cloth is cheaper than chiropractors (not to mention the ER).
