Last year I started out with an 8x8 coop with an attached 12x8 run but they also free range during the day. We added a 12 X 16 coop this year with a 16 X 6 run this year and also have a 4 x 4 coop which I have not started using yet, I am thinking about using it for a breeding pen for a few of the Langshan and possibly switch Silver Laced Wyandotte at some point when they start laying. We also have a 12 x 25 foot Turkey pen and will be reworking a 8 x 60 foot dog run to be used for Turkey as well. Good thing I have 3 - 8 x 60 ft dog runs I may need to rework a couple more.
