How much run room would I need for 15 chickens, 6 ducks, 2 geese and 2 turkeys? I've got my coop designed and will be providing the water fowl with dog house sized housing. I'll be starting on the permanent coop soon and after that the water fowl housing. We'll be making the run out of wooden frame wrapped in field fencing with chicken wire on the bottom. I've been told that turkeys will drowned themselves so the water fowl will be on one side and the turkeys and chickens on the other.
