Chicken Runs: Woodchips or Sand or Straw?
Last Updated: 26 October 2026
Quick Summary
Woodchips are the best ground cover for most chicken runs: they drain freely, support invertebrates your birds can hunt, and outlast sand or straw. In chicken runs, sand and straw do not drain and begin to smell after a month or two and a week or two respectively, while gravel is unsuitable because birds dislike it and it is hard on their feet.
- Chunky woodchips let rainwater pass straight through, so the surface stays dry underfoot.
- Hens turn woodchips over to find invertebrates, which keeps the surface aerated.
- Our chunky conifer chips come in 60L bags, UK-sourced virgin wood, 10-40 mm, with minimal dust.
- Stop mud by raising the ground with hardcore, covering the run, and redirecting runoff with a channel or French drain.
- Fresh straw over mud traps moisture and worsens the smell within days.

Best Ground Cover for a Chicken Run: Woodchips, Sand or Straw
Woodchips are the best ground cover for most chicken runs: they drain freely, support invertebrates your birds can hunt, and outlast sand or straw. Chartley Chucks (Staffordshire) explains how chicken runs behave with each material, woodchips let water through, while sand and straw hold it and then smell.
| Material | Drainage | Smell | Good for Feet? |
|---|---|---|---|
| Woodchips | Free draining | Stays fresh | Yes |
| Sand | Does not drain | After a month or two | Yes, if kept dry |
| Straw | Does not drain | After a week or two | Yes, but mats down |
| Gravel | Drains well | Stays fresh | No, birds dislike it |
Woodchips: free draining, good for invertebrates. Sand: does not drain, smells after a month or two. Straw: does not drain, smells after a week or two. If you want to try straw, Swish Fresh Rape Straw is the option compared here.
Gravel is not suitable for chicken runs: birds dislike it and it is hard on their feet.

Woodchips also support invertebrates; hens spend hours turning chips over to find them, keeping busy and the surface aerated. Our wood chips for chicken runs are chunky conifer chips in 60L bags, UK-sourced virgin wood, 10-40 mm, minimal dust, with UK delivery and collection available if you would rather pick your bags up in person. In a small, enclosed run, chips can compact if they never dry out, keep it open to air and top up regularly.
Chicken Run Drainage and How to Stop a Chicken Run Getting Muddy
Stopping mud is about moving water away, not adding bedding: raise the ground with hardcore under the chips, cover the run with a roof or tarpaulin, and redirect runoff with a channel or French drain. For metal runs, tarpaulins for metal runs can keep the rain off and reduce mud. You can also browse poultry runs to improve drainage in your setup. For more on wet weather and chickens, see our dedicated guidance.
If you are weighing up bedding and drainage for your own setup, our advice on keeping and care of chickens, a 30-minute chat, can help you settle on the right approach. Fresh straw over mud traps moisture and worsens the smell within days.
Frequently Asked Questions
Are woodchips, sand or straw best for a chicken run?
For most garden runs, woodchips are the best all-round choice. They drain freely, so surface water passes through instead of sitting on top, and they support the invertebrates chickens like to scratch for. Sand does not drain and starts to smell after a month or two, while straw does not drain and smells after a week or two. If mud is your main problem, woodchips give you the longest-lasting, lowest-odour surface of the three.
Why do sand and straw smell in a chicken run?
Neither material lets water through. Sand compacts into a solid layer, so droppings and rain sit on the surface and the run starts to smell after a month or two. Straw holds moisture in the straw itself and breaks down quickly, with odour appearing after a week or two. Woodchips avoid this because the gaps between chips let water drain away and the surface stays drier for longer.
Is gravel suitable for a chicken run floor?
No. Chickens do not like walking on gravel, and the hard, loose stones are not good for their feet over time. It also offers nothing for them to scratch and forage in, which is a big part of natural chicken behaviour. Stick to woodchips for a run surface and keep gravel for paths and drainage edges instead.
Muddy runs and smelly bedding are the two problems we hear about most, and both trace back to drainage.
