The Importance of Outdoor Space
A chicken run provides a safe, predator-proof area for your flock to exercise, dust bathe, forage, and enjoy the sunshine without completely destroying your garden. The general rule of thumb for outdoor run space is 10 square feet per chicken, but more is always better.
How Free-Ranging Changes the Math
If you allow your chickens to "free-range" (roam completely unrestricted around your yard or pasture) for several hours every day, their run size requirements drop significantly.
- No Free-Range Time: Minimum 10 sq ft per standard bird. The run is their entire outdoor world.
- Part-Time Free-Range (2-4 hrs/day): Minimum 6-8 sq ft per bird. The run serves as a partial-day holding pen.
- Full-Time Free-Range (All Day): Minimum 4-5 sq ft per bird. The run is primarily used as an emergency enclosure or morning staging area before you let them out.
Fencing and Predator Protection
Your run is only as good as its fencing. To keep your flock safe from raccoons, foxes, dogs, and hawks:
- Use Hardware Cloth: Never use traditional "chicken wire" for the bottom 3 feet of a run. Predators can easily tear through or reach through chicken wire. Use 1/2 inch welded hardware cloth instead.
- Bury the Wire: Dig a trench 12 inches deep around the perimeter of the run and bury the hardware cloth. Alternatively, lay an 18-inch "apron" of wire outward on the ground from the base of the run to stop digging predators.
- Cover the Top: A secure roof or heavy-duty netting prevents aerial attacks from hawks and owls.
Design Pro Tip: If possible, design your run with a minimum width of 4-6 feet. Narrow runs restrict the ability of chickens to walk past one another without confrontation, leading to cornering and bullying.
