Last year I put up a few plastic wall in part of the chicken run to give the birds a place to run around in the winter. I noticed the front didn't have a slop and I had to use the roof rack a few times, the back side wasn't that much better. So an upgrade was in order. I just made the front the same pitch as the other roof and a little steeper slop on the back. It will be a bit easier to use the roof rack there. Here is what came out of the upgrade.
