Should I say something about this coop?

My neighbor's landlord told her she couldn't have chickens after she'd just gotten the coop set up. So I told her she could move the coop onto our property. She does everything: cleaning, feeding, collecting the eggs, etc.

Now that it's warmer out, my 4-year-old son has been playing by the coop a lot. And I started to wonder if all the shavings and poop spilling out is unhygienic? Or is that normal? (We don't have a big yard so it'd be hard to keep him away.)

My neighbor is a single mom, so I don't want to ask her to clean it if it's unnecessary. But I also don't want to expose my son (or myself, as I am pregnant) to anything either.

I guess I'm hoping y'all can help me determine: Does this coop pose any risk? And if so, what solution would you propose?
