Weathering and the horrible ice storm we had this winter took a toll on my runs. I have slooping roofs and muddy runs that will not dry up. I want to start working on my runs next week...So all I have went through I figured I'd use red pine shavings in the run to cure the muddy runs. Will this work? I was told that laying down cardboard first. Then laying down the red pine shavings to cure muddy runs. Now for the slooping roofs I have some wire poles that came out of a old umbrella. I intend on hammering them in the ground and then bending them and attaching them to the slooping parts of the roof to pull the roofs up. Will this work or am I wasting my time. I am trying to fix everything without spending too much money so far on everything I have gotten to fix the roofs and floors and add new nesting boxes has ran me about $20. Any advice is welcome!
