Chicken run flooring: what to put on the ground

For most backyard runs the answer is coarse wood chips over a graded, free-draining base, topped up once or twice a year. They drain, they compost, hens love scratching through them, and they are the cheapest material that does not turn to slurry. Coarse sand is the better answer if your run is covered and your soil is heavy clay. Bare grass is the one choice that is guaranteed to fail: a flock strips a fixed run to dirt in a few weeks, and dirt plus rain is mud.

That is the short version. The longer version matters because almost every run-floor complaint — the smell, the flies, the mud that never dries, the birds tracking it into the nest boxes — traces back to water that has nowhere to go rather than to the material on top of it.

Why the ground is the problem, not the covering

A run concentrates a flock's droppings and foot traffic onto a small area, and extension housing guidance treats a well-drained site as a basic requirement rather than a refinement. Put a run in the lowest corner of the garden and no floor material will save it. Put it on a slight slope with somewhere for water to leave, and almost any material works.

Two pieces of groundwork pay for themselves before you spend anything on surfacing:

1. Grade the run so water leaves it. A fall of an inch or two across the run, away from the coop, is enough. If the run sits in a hollow, dig a shallow channel out of the low side.
2. Get the roof water away. Coop and run roof runoff is far more water than rainfall on the run itself. A gutter and a length of downpipe discharging outside the run will do more for mud than any amount of wood chips.

The materials, honestly compared

What to look for in a run surface

1. It has to drain, not absorb. Anything that holds water holds smell. Coarse beats fine in every material family.
2. It has to be rakeable. You will be moving droppings around weekly. Pea gravel and matted shavings both fail this.
3. It has to be kind to feet. Bare wire and thin gravel both cause sores. Litter over a hard base is the compromise.
4. It should compost. Wood chips and shavings go on the garden at the end. Sand and gravel do not, which is a real cost over years.
5. It should not blow away. Open-sided runs lose light bedding in the first gale.

What helps

Two interlocking mat options for a small or permanently wet area, the apron mesh that stops digging under whatever you lay, and the bedding that belongs on the dry side of the coop door.

9.7/10★★★★★Assessed on specs and owner reports

A narrow 16-inch roll of the same half-inch, 19-gauge hot-dipped mesh. Sixteen inches is exactly the width you want for a predator apron laid flat around the base of a run.

Small Pet Select Pine Shavings Chicken Bedding

Small Pet Select

9.2/10★★★★◐Assessed on specs and owner reports

Kiln-dried pine shavings in a bag sized for a coop rather than a hamster cage. Pine is the baseline bedding for a reason: absorbent, cheap, compostable, and it does not mat.

Specifications per Manufacturer figures as published on the Amazon product listing, as published at the date above.

Why we picked it

• Absorbent enough to run a deep-litter floor for weeks between full changes
• Composts down with the manure into usable garden material
• Shavings stay loose, so hens can scratch and dust-bathe in them

Good to know — Dustier than hemp, which matters in a tight coop with poor ventilation

Mats, and what they are actually for

Interlocking plastic floor pads are not a run surface in the way sand or chips are. They are a way to lift birds off ground that stays wet, inside a small coop or under a covered section, and they come out to be hosed down. In a 100 sq ft open run they are the wrong tool: you would need a great many of them, and the droppings still end up on whatever is underneath.

Where they earn their place is the covered patch immediately outside the coop door, which takes the heaviest traffic and stays wettest. Pave that with mats or slabs, surface the rest with chips, and the run behaves far better than it does with a single material everywhere.

The dig barrier underneath

Whatever goes on top, the perimeter is where predators work. A hardware cloth apron laid flat on the ground outside the run and pinned down, then covered with the run surfacing, stops a digging fox or dog without any digging of your own. This is the single highest-value thing to do while the run floor is already open.

Deep litter in the run

Adding carbon — chips, leaves, straw — on top of droppings rather than removing them works outdoors as well as in. The litter composts in place, which is why a well-chipped run smells of woodland rather than ammonia. Two rules make it work: keep adding material before it looks like it needs it, and keep it dry enough to compost aerobically. A run that is permanently wet does not compost, it ferments, and the smell tells you which is happening.

Mud in winter: the short checklist

• Roof water diverted outside the run.
• Six inches or more of coarse chips on the traffic routes.
• A covered section the birds can stand in on a wet day. A cover over even a third of the run changes the whole floor.
• Droppings raked out of the heaviest-traffic strip weekly rather than monthly.
• No feeder or waterer on the muddiest ground — move them onto a paver or a mat and the mud stops spreading.
