so i'm adding an additional run for my hens and I'm torn between covering all of it and leaving some exposed to the sun... and rain. I swore off leaving any part uncovered when I built my coop a couple of years ago but I just feel so bad that our hens rarely get to be out in the open and yet, the rain here tends to cause a nasty mess when it comes to chicken runs. I'm contemplating using transparent roofing for a panel or two and maybe leaving one two ft by eight ft stretch uncovered. has anyone had luck with leaving some part of their run in the northwest exposed to the elements. any tips would be appreciated!
