For backyard chicken owners, ensuring the safety and well-being of their feathered companions is a top priority. One common concern that comes up every spring is whether mulch is safe for chickens. Whether you’re using mulch around your landscaping or considering putting it in their coop or run, you’ve probably asked yourself, is mulch safe for chickens?

There are a variety of mulch options available and it’s a good idea to consider their potential effects on poultry health. In this article, we’ll explore different types of mulch, their suitability for chicken runs, and best practices to keep your flock happy and healthy.

Understanding Mulch and Its Varieties

Mulch serves various purposes, from retaining moisture to suppressing weeds and enriching soil. Different types of mulch include organic materials like pine needles, grass clippings, and wood shavings, as well as inorganic options like rubber mulch and river rocks. While organic mulches provide nutrients as they decompose, inorganic mulches offer longevity and low maintenance.

Most Common Types of Mulch

1. Wood Mulch
   • Wood Chips: Made from shredded or chipped wood, wood chips are versatile and widely used for mulching garden beds, pathways, and landscape areas. They come in various sizes and are available in different wood types such as pine, cedar mulch, cypress mulch, and hardwood chips.
   • Bark Mulch: Bark mulch is made from the outer bark of trees and is available in different textures and colors. It’s popular for its attractive appearance, ability to retain moisture, and effectiveness in suppressing weeds.
2. Organic Mulch
   • Straw: Straw is a common organic mulch made from dried cereal grain stalks. It’s lightweight, inexpensive, and helps retain soil moisture. Straw is often used in vegetable gardens and around newly planted seedlings.
   • Grass Clippings: Grass clippings from mowing your lawn can be used as mulch. They decompose quickly, add nutrients to the soil, and help suppress weeds. Make sure the clippings are free of herbicides and pesticides.
   • Leaves: Fallen leaves can be collected and used as mulch. They decompose over time, adding organic matter to the soil and improving soil structure. Shredding the leaves before applying them as mulch can help prevent matting and improve decomposition.
3. Inorganic Mulch
   • Rubber Mulch: Made from recycled rubber, rubber mulch is long-lasting and helps suppress weeds. It’s available in different colors and does not decompose, making it a low-maintenance option for landscaping.
   • Rock Mulch: Rocks or gravel can be used as mulch in areas where erosion is a concern or in xeriscaping projects. They provide good drainage, help retain soil moisture, and add texture to the landscape.
4. Living Mulch
   • Ground Covers: Low-growing plants such as clover, creeping thyme, or ground ivy can serve as living mulch. They help suppress weeds, reduce soil erosion, and add beauty to garden beds.
   • Cover Crops: Cover crops such as clover, vetch, or rye can be planted to cover bare soil and provide mulching benefits. They add organic matter to the soil, improve soil structure, and help suppress weeds.

These are just a few examples of the most common types of mulch used in gardening and landscaping. Each type has its advantages and considerations, so it’s essential to choose the right mulch for your specific needs and preferences.

​Landscaping Mulch and Your Free-Range Chickens

It’s essential to be cautious when using landscaping mulch around areas where chickens roam, such as chicken runs or free range areas. While some types of mulch can be safe for chickens, others may pose risks to their health if ingested or come into contact with their environment. Here are some considerations to keep in mind.

1. Toxicity: Certain types of mulch, such as those made from cedar, black walnut, or other toxic plants, can contain compounds that are harmful to chickens if ingested. These toxins can cause digestive upset, respiratory issues, or other health problems. It’s crucial to research the specific type of mulch and its potential effects on poultry before using it in areas accessible to chickens.
2. Ingestion Risks: Chickens are curious creatures that may peck at or ingest mulch materials. Sharp or splintery mulch, such as wood chips or shredded bark, can pose ingestion risks, leading to digestive blockages or injuries. Avoid using mulch with large, sharp pieces that could be swallowed by chickens.
3. Respiratory Issues: Fine particles from certain types of mulch, especially cedar or pine shavings, can create dust that may irritate chickens’ respiratory systems, particularly in enclosed areas like coops or runs. Choose mulch materials with larger particle sizes or lower dust content to minimize respiratory risks.
4. Environmental Contamination: Mulch treated with chemicals or pesticides can leach into the soil and water, potentially contaminating the environment and affecting chickens’ health. Avoid using chemically treated mulch in areas where chickens have access, as they may come into contact with the chemicals through pecking or dust bathing.
5. Alternative Options: If you’re concerned about the safety of landscaping mulch around your chickens, consider using alternative ground cover materials such as straw, grass clippings, or untreated wood chips. These materials are generally safer for chickens and can provide similar benefits for soil health and weed control.
6. Regular Monitoring: Keep a close eye on your chickens’ behavior and health after introducing landscaping mulch to their environment. Watch for signs of ingestion, respiratory distress, or other health issues that may indicate the need to remove or replace the mulch.

Overall, while landscaping mulch can be a useful tool for gardeners and landscapers, it’s essential to prioritize the health and safety of your chickens when using mulch in areas where they roam. By choosing safe mulch materials and monitoring your chickens’ well-being, you can create a healthy and enjoyable environment for your flock to thrive.

Should you use Mulch in the Chicken Run?

Using mulch in a chicken run may not be the best option, but it can offer several benefits. Timing, however, is crucial to ensure it’s done effectively and safely for your flock. Here are some considerations for when to use mulch in a chicken run.

 Best Practices: Ensure mulch safety for your chickens.

1. Choose Safe Materials: Opt for chicken-safe mulch materials like pine needles, straw, or untreated wood chips. Avoid mulches containing aromatic compounds or toxic substances.
2. Proper Installation: Apply mulch in areas with good drainage to prevent moisture buildup, which can attract pests and cause health issues. Use hardware cloth or wire mesh to cover mulched areas if necessary.
3. Regular Monitoring: Keep an eye on your chickens’ behavior and health after introducing mulch to their environment. Watch for signs of ingestion, respiratory distress, or pest infestation.
4. Rotation and Maintenance: Rotate mulch regularly to prevent compaction and mold growth. Incorporate chicken waste into compost piles to recycle nutrients and minimize odor.
5. Consider Alternatives: Cover crops or river rocks are some of the best ground cover that provide benefits without the risks associated with traditional mulches.
6. Established Run: It’s best to wait until your chicken run is established before applying mulch. This means that your coop and run are fully set up, and your chickens have been living in the space for some time. This allows you to observe their behavior and ensure they are comfortable and healthy before adding mulch.
7. Dry Weather: Ideally, apply mulch during a period of dry weather. Wet mulch can become heavy and clumpy, making it less effective and potentially creating muddy conditions in the run. Waiting for dry weather also reduces the risk of mold or fungal growth in the mulch.
8. After Coop Cleaning: Consider applying mulch after cleaning out your chicken coop. This ensures that the run is clean and free of debris before adding the mulch layer. It also allows you to refresh the bedding material in the coop at the same time.
9. Toxicity: Certain types of mulch, such as cedar shavings or mulch from toxic plants, contain compounds harmful to chickens. Avoid using these materials in areas accessible to your flock to prevent health problems.
10. Respiratory Problems: Fine particles from mulch, especially cedar or pine shavings, can contribute to respiratory illness in chickens, particularly in enclosed spaces like coops or runs. Proper ventilation and choosing less dusty mulch options can mitigate this risk.
11. Ingestion Risks: Chickens may peck at mulch, potentially ingesting harmful materials or causing digestive blockages. Opt for mulches with larger particle sizes or use barriers to limit access to mulched areas.
12. Health Problems: Wet mulch, such as wet leaves or grass clippings, can create breeding grounds for bacteria and pests, leading to health problems for chickens. Regular maintenance and proper drainage can help mitigate these risks.

Overall, using mulch in a chicken run can provide benefits such as improved soil health, moisture retention, and pest control. By timing the application carefully and choosing safe materials, you can create a comfortable and healthy environment for your flock to enjoy.

Other Material Options for the Run

When it comes to choosing the best material options for a chicken run, several factors should be considered, including safety, durability, ease of maintenance, and suitability for the chickens’ natural behaviors. Here are some top material options for chicken runs.

Grass: Allowing grass to grow in the chicken run provides a natural surface for chickens to forage, scratch, and dust bathe. Grass is a good choice as it also helps absorb moisture and reduces mud in the run. However, in my experience, grass doesn’t last long in chicken runs.

Sand: Sand is a great option for chicken runs as it is easy to clean, provides good drainage, and allows chickens to dust bathe naturally. Sand also discourages the growth of parasites like mites and lice. Regular raking will help keep it clean and prevent odor buildup.

Pea Gravel: Pea gravel is another good option for chicken runs. It provides excellent drainage, reduces mud, and is relatively easy to clean. However, small stones may pose a choking hazard to chickens, so choose a size that is large enough to prevent ingestion.

Wood Chips or Shavings: Wood chips or shavings are commonly used as ground cover in chicken runs. They provide a soft surface for chickens to walk on, absorb moisture, and decompose over time, adding organic matter to the soil. Use untreated wood chips to avoid any potential toxicity issues. Just be cautious of mold.

Pine Needles: Pine needles are lightweight, easy to spread, and provide a natural surface for chickens to scratch and forage. They also have natural antimicrobial properties that can help keep the run clean and reduce odor.

Rubber Mulch: Rubber mulch is a durable and long-lasting option for chicken runs. It provides good traction, reduces mud, and is easy to clean. However, it may contain chemicals that could be harmful to chickens if ingested, so choose a non-toxic, rubber mulch specifically designed for use with animals.

Dirt or Soil: Some chicken keepers, like me, choose to leave the run floor as bare dirt or soil. While this option is natural and inexpensive, you may end up with a muddy run in wet weather and require regular maintenance to prevent erosion and odor. We have a roof on our run, so we only deal with a muddy run during bad storms.

Hardware Cloth or Wire Mesh: In addition to a ground cover material, it’s essential to consider the flooring structure of the chicken run. Installing hardware cloth or wire mesh underneath the ground cover can help prevent predators from digging into the run and protect your chickens from harm.

Bottom Line

While mulch offers benefits for soil health and weed control, its safety for free-range chickens depends on factors such as material type, installation method, and regular maintenance. By choosing chicken-safe mulch materials, practicing proper installation techniques, and monitoring your flock’s health, you can create a safe and enriching environment for your backyard chickens. Prioritize their well-being to ensure they thrive in their chicken run for years to come.
