I was at Costco today, they have a plastic tool shed (kit) that is 6X8 and has a window and double doors and an integral gutter system with a fitting so you could attach a hose to gather water. $650 for those who have no time or are lacking in know how.
Wish I'd found it b-4 I starte building...
A buddy of mine came up with a ton of used metal siding (delta Rib style). There is enough for roof and all walls inside and out. Even enough to bury at the perimeter of the run.
I have windows at both ends and a door to leave open in good weather, so I don't feel ventilation is a problem...
So, I'm a handy sort but have no idea how to "structure" the inside. Roosts of 10" per chx, 12" from a parallel wall, 24" off floor?? Have a 43" X 120" space. So it's long and narrow and only have access to one side and one end. Probably only room for one long perch across back. Do chx need much...
