Hello Folks. Unique Situation here and need some help rather badly. Our 25 x 25 chicken run is alongside our barn, and is under/ next to a tree which drops leaves and branches into the run (if they don't get caught in the aviary netting.) The run is on a slant so when theres water it pushes all the dirt, silt, leaves, sticks, etc down to the bottom of the run. The bottom is where there is a dutch door we use to enter the run and clean it, give chickens treats, etc. The dirt and buildup is blocking the door in a way that it can barely be opened, which is bad!!! How can I make it so it will be more easily accessible and also provide bedding to the run (probably sand) without it all washing downhill? Thanks for the help.!
