So if you need 1/2 inch mesh predator apron, then everything else had better be 1/5 inch mesh or smaller.
@Celticdragonfly has 1/2" all over her great looking coop and run. It will be well worth all the cuts and aggravation putting down a 1/2" HWC apron in the end.
That's exactly what my whole coop and run are made out of, 1/2" HWC. My coop and run are open 24/7, I sleep well at night, go on vacation for a week at a time, don't worry about them and nobody has to come and let them out or lock them up at night.
