For the first two years of my chickening adventures, I used pine shavings as litter inside the coop primarily because they were a common recommendation that was readily available at my local Tractor Supply Store fairly inexpensively. It never occurred to me to use sand inside the chicken coop even though I used sand in the run, but when
fan Kelly V. enthusiastically vouched for sand's performance in her chicken coops, I
had plenty of sand on-hand already, so I figured it couldn’t hurt to experiment.
Worst case scenario, I could scoop it out into the run and return to using pine
shavings. Pine shavings are a very good litter choice, but scientific research
and personal experience has proven that sand is even better!
As it turns out, sand is not a novel or modern chicken litter concept; the use of sand is a tried-and-true, old timer's method of raising laying hens. Poultry visionary, Charles Weeks wrote of the benefits of sand as chicken litter in his 1919 book, "Egg Farming in California,” in which he stated: “Sand is the only material to use on the floors of poultry houses. Clean, dry sand prevents any bacteria from starting. Clean, sharp sand is the freest from dust and easy to keep clean, as the droppings lay on top and are easily lifted off.”
In scientific studies done by the Auburn University Department of Poultry Science, which were borne out by further field testing, sand proved to be better than pine shavings with lower bacterial counts, lower fungal populations and lower moisture levels. The
Auburn research states, “Sand, being
inorganic, contains few nutrients that could be utilized by bacteria and, thus,
would tend to lead to lower bacterial numbers.” “Additionally, sand may lack
binding sites for bacteria.” Straw is a poor choice for litter due to its notorious lack of absorbency, tendency to cause crop impaction,
propensity to form manure mats, and inability to control moisture, insects,
bacteria levels and ammonia. Similarly, hardwoods shavings such as beech should
be avoided due to their propensity to harbor disease causing molds and fungus
as well as containing toxic phenol fumes. The last thing I wanted in my coop was a droppings-laden mat of respiratory trouble for my chickens.
The benefits of sand are many. Sand desiccates droppings, it does not retain moisture or decay inside the coop, which means less risk of respiratory infections, fewer flies and other insect activity, less bacterial growth, reduced bumblefoot infections and a lower risk of frostbite compared to shavings and straw. There is no risk of crop impaction with sand, in fact, sand is beneficial to the digestive tract since it is used as grit in the gizzard to break down fibrous foods before being passed in the droppings. Due to its high thermal mass, sand maintains more stable coop temperatures; the
found that sand keeps chicken houses cooler in the summer and warmer in the winter. In inclement weather, sand inside the coop is dry and dust-bath ready!

Aesthetically, sand looks cleaner than other litter options and is cleaner; the
researchers found coliform counts, including E.coli, significantly lower in sand than in wood shavings. Auburn University
Sand continues to be recommended by poultry experts and veterinarians today. Maryland Poultry Veterinarian, Dr. McKillop, DVM, MSpVM, DACPV states, “Sand is a wonderful litter/ground source for backyard poultry. I advise all of my clients to go from shavings to sand. When it gets wet or rains, it drains, sand is easy to clean, and it’s a wonderful medium for dust bathing. Sand decreases Coccidiosis problems because coccia require warm, damp environments with oxygen to sporulate.” Chickens are able to acquire a natural immunity to coccidiosis gradually without contracting the intestinal disease from an overpopulation of disease-causing oocysts promoted by wet litter.
In her book, Hatchingand Brooding Your Own Chicks, esteemed poultry author Gail Damerow discusses sand as brooder bedding, saying, “(Sand) is not as absorbent as other types of bedding, but it absorbs heat more readily and evaporates moisture more rapidly and therefore stays drier. Perhaps for the same reason, sand is more resistant to microbes than other types of bedding, keeping baby birds healthier. Soiled sand doesn't stick to feet like other types of bedding can. When it is kicked into a drinker, sand doesn't float and discourage drinking but rather sinks to the bottom so the water remains clean. Provided it is sifted periodically to remove chick poops, sand lasts much longer than other types of bedding, making it extremely economical.” While it is uncommon for baby chicks to ingest litter when feed is available, it’s better to allow them to become accustomed to starter feed for a few days before introducing any litter into the brooder, opting for paper towels instead.
THE IMPORTANCE OF SAND TYPE
The correct sand type goes by a great many names, washed construction grade sand, bank run sand, river sand, etc. The construction supply company I get my sand has changed what they call it from year-to-year, so when sourcing sand, it’s better to see or describe the desired product rather than insist on a certain label. Sand for use as chicken litter and dust baths should be natural and consist of variable particle sizes. Coop sand should not be manufactured by crushing. Many play sands are manufactured by crushing quartz, which creates fine, dusty particles that pack closely together, neither of which are desirable features for chicken litter. Further, manufactured sands contain a much higher percentage of free silica than natural sands, which can pose a respiratory hazard to humans and animals over time. Steer clear of manufactured sands.
Sand can be purchased in bulk at local quarries relatively inexpensively. Every community has a local source of sand for use in construction and landscaping projects. Garden centers, landscaping and construction companies are all good sources too. Home improvement centers usually carry bags of sand at a less economical prices than bulk sand, but caution must be used to be certain the sand is natural, not manufactured. Newly delivered sand is typically moist from being washed and stored outside. In warm weather, it will dry quickly; raking the sand a few times during the day facilitates drying. Any water spills can be easily handled by raking the wet sand into the dry sand or simply shoveling the affected sand out of the coop. Any residual moisture from spills dissipates very quickly.
TIPS FOR USING SAND
The drier and cleaner a coop is kept, the healthier the environment for the flock. With all litter types, it is infinitely better not to keep the flock's drinking water inside the coop. Encourage outdoor activity and a healthy coop by placing water and feed in the chicken yard, which should also eliminate any rodent activity and reduce the fly population in the coop significantly.
Sand can be used on coop floors that are cement, dirt, or wood. Inexpensive linoleum placed on top of wood flooring before adding sand makes deep-cleaning the coop a breeze. A shovel and broom make quick work of the annual task in my coops. I use approximately 4 inches of sand inside the chicken coop and as much as a foot in the chicken run.
I recommend the use of droppings boards underneath the roost to minimize droppings inside the coop. Droppings boards are essentially a shelf that catches droppings produced from chickens roosting at night. Droppings boards are scraped off into a bucket, ordinarily first thing in the morning, then added to compost. Any stray droppings found inside the coop are easily removed with a kitty litter scoop or sifter. Once a year I remove the sand from my coops, clean the entire coop and fill it with fresh sand. Sand can be washed, dried thoroughly in the sun and reused.
The use of sand in the chicken yard or run is ideal in especially wet climates since water drains through the sand instead of creating mud puddles filled with decomposing straw or wood shavings. If possible, roof or cover the chicken run to keep the sand dry and provide the flock an outdoor oasis in inclement weather. Should sand in the chicken run get wet from drinking water, blowing snow or rain, using a roto-tiller or shovel to turn it facilitates drying and keeps the sand fresh and mobile.
THE CHICKEN RUN
Our chicken run is covered by a roof, but with open sides, rain gets the sand wet from time-to-time. When that happens, I either use a shovel to turn it or roto-tiller to freshen it up. Since it dries up so quickly, once turned, it breaks up easily. Sweet PDZ (aks: zeolite) added to litter in the chicken coop helps further control odors, ammonia, moisture and flies. Much more information on the benefits of Sweet PDZ in the coop and run HERE.
The one disadvantage to sand is its weight. Sand is heavy and may not be a feasible option for physically limited chicken keepers or in large chicken tractors.
BENEFITS OF SAND INSIDE THE COOPS AT-A-GLANCE
- desiccates droppings
- does not retain moisture
- does not decay or degrade inside the coop
- superior drainage
- natural grit
- no risk of crop impaction as with straw and hay
- easy daily maintenance
- infrequent deep cleaning required
- keeps feet clean and nails manicured
- cleaner feet=cleaner eggs
- any dropped feed gets eaten, not lost in the litter
- dust-bath Mecca
- no decomposition required in compost pile/great soil amendment especially in clay-heavy
- keeps coops cooler in the summer and warmer in winter due to its high thermal mass
- reduces the risk of frostbite
- looks cleaner than other litter options and it is cleaner than other litter choice
DRAWBACKS OF SAND INSIDE THE COOPS
- heavy to move
- dusty, but so are pine shavings, straw...and chickens, for that matter!
One of the benefits of sand in a covered run is that chickens can dust-bathe all year long. Dry sand sand stays loose even in the coldest temperatures. This photo was taken in the middle of winter during a week with sub-zero temperatures.
