I have recently discovered that even moving our tractor everyday with just two hens it is still not enough. They are tearing up the grass and leaving big muddy holes where they had dust baths. This is the same coop as mine: https://www.backyardchickens.com/a/the-garden-ark I'm just wondering if there is any quick growing and hearty grass I can plant, or is it better to create a floor? And if so with what? A friend suggested I build a box and put soft dirt in for a bath to help slow down the digging. I'm just trying to avoid having the yard torn up while still providing them a nice setting. If anyone has any information it would be greatly appreciated.
