Do any of you actively do pasture management in the barnyard?

In other words, when bare dirt areas form, do you fence it off and seed it?

I'd be interested in knowing how you manage this, and how you decide what to plant. I've got chickens, ducks, and geese (24 total) in a yard that's about 2500 square feet on a hill going down from the barn. Parts of it are sometimes a little shady, and in some parts of the year, a small section gets a little wet.
