plants for inside a run help needed please

hi, i would like to put a few plants inside my chicken run for a few reasons,
1, to soak up any water when it rains as we get the run of from other plots,
2, to make it look nice
3, to make it smell nice(some herbs that grow large may be)
4, also to act as a wind breaker, i have metal and plastic sheeting all around and it works but it's not nice to look at,

any idea's please thankyou,

what about fruit trees small 1's ,

I have planted fruit trees inside my run and they are fine and doing well (3 years on). Depending on the size when you plant them you may need to protect the trunk and possibly the tops if they are very small.

I have rosemary and mint bushes in mine, which they leave alone, and 2 pear trees with clematis climbing through them which they don't touch either, unfortunately they did like wallflowers, but they looked nice for a day lol alison
