Thanks so much for the response and suggestions! They are much appreciated . Unfortunately we don't have any other stuff to put in the run at the moment (I went over budget this Christmas .) Just eucalyptus. So, I loaded up the wheelbarrow with the leaves and wheeled 'em to the run and realized I needed to dig a trench to redirect the water. There WAS run off as we are on a slight slope and the coops & run are down below. I don't think the leaves would have made a difference really so I didn't use them. So far the trench is working well and I look forward to checking out the link you posted. Thanks again!
Try contacting tree removal and trimming companies and see if they will dump a load of wood chips for you to use, after a job. They'll need to get rid of them anyway.
A thick layer of wood chips seem to last longer than leaves.
Good thing you re routed the water!
