 However: there is an exception – you must not feed ryegrain and turf ryegrass to growing chickens like broilers and pullets. These varieties of ryegrass are known to affect the growth of young birds.

 Moreover, its fiber content also results in sticky excreta. It also adds a high level of moisture to the litter, which increases ammonia production. Some varieties of ryegrass also have fungi and diseases that are toxic to chickens.

Rye Grain Grass

Rye (Secale cereale) is a cereal grain plant. It produces the rye grain, which we make into flour and bake breads from. Understand that rye grain does not offer much nutritive value for chickens. This is because it interferes with fat-soluble vitamins and minerals. Therefore, you must avoid feeding rye grain, especially to younger birds like pullets and broilers.

Forage-Variety Rye Grasses

Ryegrass is the name given to a group of highly palatable and high-quality forage grasses. They are mainly planted on farms with cows and other livestock. Thus, ryegrass is a collective term for different varieties of grasses like Italian rye, perennial ryegrass, annual ryegrass, etc. 

Perennial ryegrass (Lolium perenne L.) has a good yield and is fairly easy to maintain. It is safe for chickens to forage on. Annual ryegrass is often used as turf grass. It may be treated with chemicals and endophyte fungi, so you must not plant it as it is toxic to chickens.

Benefits of Feeding Perennial Rye Grass to Chickens

Experts recommend feeding endophyte-free perennial ryegrass (Lolium perenne L.) and other forage ryegrasses in moderation to chickens. Here are some advantages to doing so:

Perennial Ryegrasses Are Hardy Winter Grasses

If you live in an area where it snows, ryegrass can provide your chickens with a great source of greens to forage on in the winter. 

Other grasses wilt away quickly in colder temperatures. The perennial ryegrass stays green and elegant and provides chickens with a constant source of greens for the colder months. Perennial ryegrass grows quickly. It is an ideal pasture grass for lactating dairy cows and other livestock. It prevents soil erosion as well.

Provides Many Nutrients to Your Birds

Chickens can safely forage on perennial ryegrass – it provides many nutrients to your birds

It is ideal for your grazing activities, which stimulate your hens mentally.

Ryegrass provides your chickens with fiber, which has many health benefits and promotes digestion in your pets. Fiber from ryegrass also ensures optimal gut function. Ryegrass also provides vitamins A and E, which are needed for healthy laying birds and nutritious eggs. It also contains almost 12-16% protein content.

Good for Laying Hens

You can allow your laying hens to forage on perennial ryegrass. Hens can eat rye grass after they have reached the age of peak egg production – about 40 weeks. The protein, fiber, and other vital nutrients are good for the birds and promote healthy eggs.

Precautions to Follow Before Feeding Ryegrass to Chickens

Not All Varieties of Ryegrass Are Safe for All Poultry  

As mentioned earlier, do not feed rye grain grass and turf annual ryegrass to young, growing birds (pullets and broilers). This is due to the presence of arabinoxylans, a non-starch polysaccharide that interferes with nutrient absorption (especially fat-soluble vitamins, minerals, etc.). This can impact the growth of the young birds.

Similarly, if you keep turkeys, please avoid feeding ryegrass to them. This is due to its low nutritional value as well as the arabinoxylans explained above.

Beware of The Presence of Fungus

Some varieties of turf ryegrasses are treated with endophyte fungi to resist pests. These endophytic fungi produce toxins and can cause various health issues in your chickens. Avoid planting such grasses if your chickens forage.

The ergot fungus causes yet another rye disease, which, in high concentrations, can also be highly toxic to animals.

Moisture Content/Sticky Excreta

Some ryegrasses enhance the stool’s sticky content and make the feces stick to the hens’ bottoms. The excess moisture in the poop also increases the ammonia in the litter. Therefore, practicing moderation is important when it comes to feeding ryegrass to chickens.

It also gives chickens a good dose of fiber, which helps with their digestion, and some nice greens to eat. These are important for keeping your birds healthy, especially when there aren’t as many fresh greens available.

Is It Safe to Feed Chickens Grass?

Feeding grass to chickens is generally safe and healthy, provided you follow some basic precautions. Chopped or cut grass, a few inches in length, is suitable for chickens and offers them a lot of nutrition. However, longer grass could pose certain health risks, such as impacted crops or impacted digestive systems in chickens. In worse case scenarios, it can even result in death.

Grass provides valuable protein to your birds, aiding in muscle development and overall health. Additionally, its fiber content supports healthy digestion and prevents gut problems. Yet, excess grass can unbalance their diet, so it’s important to offer a varied diet including grains and other nutrients.

By providing appropriately cut grass, you ensure chickens get the nutritional benefits without the risks associated with longer strands. Always monitor your birds’ grass intake and offer a balanced diet to maintain their health. This is essential to prevent potential health issues associated with excessive or long grass consumption.
