First time chicken owner here!

We had our chicken coop and run made by someone who does it for a living. We did our research and had him install hardware cloth for the run. Our chicks are only 2 days old and are not even in the coop/run yet!

I went to check on the run and coop today because we got lots of rain and I wanted to make sure the roof was done right. Well… something already climbed the run & bent the cloth/mesh?! In fact, one little square is already broken in half. Posting a photo so you can see what I mean!

What is wrong with this?! Does the chicken coop Builder need to do something different?
