Right! A run will need to be 800sqft. That’s like 20ftX40ft. Add a coop of 320sqft, put it at the 20ft end of the run, now you have an area of 20ftX56ft which is 1120sqft. That’s a darn good chunk of occupied land. Of course it won’t have grass in it, but 80 birds allowed to free range will be spilling over into neighbors yards. If you somehow fence them in successfully to keep them off neighbors yards your 1/2 acre will be stripped of all vegetation.80 chickens on less than 1/2 acre, am I understanding that correct?
How big will the run be for 80 chickens?
That's one cool coop!!
