I mulch trees in the yard, and they pull it all over the place. Here I don't care, but you might. Mulch in their yard is great! And a larger run for them?!
It's that learning curve, figuring out how you and they can co-exixt in the same spaces.

Mulch! they love to rearrange mulched planting beds, and eat some nice plants, like hostas, for example. And dig up roots around trees and shrubs. Never mind the lawn...
We have shrubs and trees next to our coop, with rocks, 2" to 6" diameter, around them to prevent the 'bare root to death'...
