Fermenting Chicken Feed
Lacto-fermentation is a simple, effective method of improving poultry nutrition, reducing feed waste, and supporting the overall health of your flock. In this post, we’ll cover what fermentation is, why it matters, and how to easily incorporate it into your routine.
What Is Lacto-Fermentation?
Lacto-fermentation occurs when naturally occurring Lactobacillus bacteria interact with food in a low-oxygen, moisture-rich environment. In chicken feed, this process transforms sugars and starches into lactic acid, which creates a lower pH and prevents the growth of harmful bacteria. It also supports the development of natural probiotics and beneficial yeasts.
To ferment feed, all you need is a clean container, such as a mason jar with cheesecloth or a food-grade bucket with a loosely fitted lid or small ventilation holes.
In about three days, the fermentation process is well underway, and the feed becomes more nutrient-dense, more digestible, and less wasteful.
Benefits of Fermenting Feed
Improved Digestion and Nutrient Absorption
Soaking and fermenting grains softens them, making them easier for chickens to digest. The process reduces phytic acid, a naturally occurring compound that can block nutrient absorption. Lowering phytic acid improves the bioavailability of minerals and vitamins such as B and C.
Probiotics and Immune Support
Fermentation increases beneficial bacteria in the feed. These probiotics improve gut health and help regulate the intestinal environment, lowering the risk of pathogens like E. coli and Salmonella. Poultry with stronger gut health tend to show improved immunity and overall resilience.
Stronger Eggshells and Better Egg Quality
According to research published in the Journal of British Poultry Science, chickens fed fermented feed produced heavier eggs with thicker shells. A proper nutritional profile reduces the likelihood of soft-shelled eggs or egg binding and results in more nutrient-rich eggs for consumption.
Lower Feed Costs
Fermented feed expands in volume, meaning your flock fills up faster on less product. For example, five chickens eating 2.5 pounds of dry feed per day may consume one 50-pound bag every 20 days. With fermented feed, that consumption can be cut in half—significantly lowering costs while improving nutritional output.
How Often to Feed Fermented Feed
Frequency is flexible. Some keepers feed fermented feed daily, while others offer it two to three times a week or during times of stress, illness, or environmental change. There’s no strict limit. The more often it’s offered, the more benefits your flock receives.
How to Ferment Feed
1. Choose a Container
Use a mason jar with cheesecloth or a 3-pound plastic pail (drilled with small holes in the lid for ventilation). Avoid sealed containers, as fermentation produces gas that needs to escape.
2. Add Feed and Water
Fill the container halfway with feed. Cover the feed completely with distilled or purified water, leaving space for expansion. Stir thoroughly from bottom to top and loosely cover.
3. Stir and Maintain
Stir every 12 hours. After about 3 days, the water may be mostly absorbed. Add more if needed to keep the feed moist but not soupy. A slight sour smell is normal—if it smells rotten or moldy, discard and start over.
4. Feed and Reuse
Scoop out only what your chickens will eat in a day. Reserve some of the liquid (called the “brine”) to jumpstart your next batch. In warm weather, refrigerate leftovers. In cold weather, they can safely remain out for a day or two.
Final Thoughts
Fermenting chicken feed is a practical, cost-effective step that improves poultry health, strengthens eggs, and enhances feed efficiency. While it takes a bit of extra time, the long-term benefits make it a valuable practice for any serious flock owner.
Happy chicken keeping,
