The container must be able to be covered to prevent contamination but should also allow for the escape of gases produced during fermentation.

Step 3: Water to Feed Ratio

Achieving the right water to feed ratio is essential for proper fermentation. The recommended ratio is generally 2 parts water to 1 part feed, which ensures the feed is fully submerged.

It’s important to observe the amount consumed by the chickens to make necessary adjustments for future batches, ensuring that the feed is neither over nor under-supplied.

Step 6: Continuous Fermentation

To maintain a steady supply of fermented feed, continue the fermentation process by adding fresh feed and water to the container after each feeding, following the established water to feed ratio. This practice ensures a consistent and ongoing supply of fermented feed for the flock.

Step 7: Observation and Adjustment

Regular monitoring of the flock’s response to the fermented feed is vital. Indicators of success include healthy, vigorous birds with good appetites and shiny feathers.

This involves keeping the fermentation vessel clean, ensuring the feed and water added are free from contaminants, and regularly checking the feed for any signs of spoilage.

Comparing Fermented Feed to Conventional Feeding Methods

Fermented chicken feed stands out for its ability to improve flock health and reduce feed costs. Unlike dry feed, fermented feed boasts increased bioavailability of nutrients and introduces beneficial probiotics to the chickens’ gut flora, leading to better digestion and nutrient absorption. Furthermore, the slight acidity of fermented feed helps deter harmful pathogens, offering a natural way to boost the immune system.

Comparison Table Between Fermented Feed and Conventional Feed

FeaturesFermented FeedConventional Feed
Nutritional ValueHigher, due to increased bioavailability of nutrients and addition of probiotics.Lower, as nutrients are in their original state and may be less bioavailable.
DigestibilityImproved, as fermentation breaks down anti-nutrients and complex proteins.Standard, as feed is not pre-digested or broken down.
Immune System SupportEnhanced, due to the introduction of beneficial bacteria to the gut flora.Limited, as feed does not naturally include probiotics.
Feed EfficiencyHigher, chickens require less feed due to improved nutrient absorption.Lower, as chickens may require more feed to obtain the same nutritional benefits.
Cost Over TimePotentially lower, due to reduced feed quantity needs and improved health reducing veterinary costs.Higher, considering the potential for increased feed consumption and health-related expenses.
Preparation TimeRequires initial setup and daily maintenance for fermentation.Minimal, as feed is used directly from the bag without additional preparation.
Waste ReductionLower waste, as chickens tend to spill less fermented feed and absorb more nutrients.Higher waste, due to spillage and less efficient digestion.
Health IssuesReduced risk of diseases thanks to a healthier gut environment and the antibacterial properties of fermented feed.Standard risk, without the added health benefits of fermentation.

Pros and Cons Based on Firsthand Experience

From personal trials and careful observation, the benefits of fermented chicken feed have significantly outweighed any drawbacks. However, it’s important to present a balanced view based on real-life application.


  • Enhanced Nutrient Absorption: Fermentation breaks down phytates and other antinutrients, making vitamins and minerals more accessible.
  • Improved Gut Health: The probiotics generated during fermentation promote a healthy digestive system.
  • Reduced Feed Waste: Chickens tend to spill less fermented feed, and its increased nutrient density means they need to consume less.
  • Cost Efficiency: Although the initial setup requires time and effort, the long-term savings on feed costs are notable.


  • Daily Maintenance: The fermentation process requires daily attention to ensure the feed remains submerged and free from contamination.
  • Initial Learning Curve: Perfecting the fermentation process to suit specific flock needs can take time and adjustment.

Making An Informed Decision

Based on extensive experience and research, fermented chicken feed offers a compelling array of benefits for poultry health, welfare, and farm efficiency. While it demands a certain level of commitment and oversight, the outcomes—in terms of bird health, productivity, and feed cost savings—strongly justify the investment.

Expert Recommendations for Best Results

To achieve the best outcomes from fermenting chicken feed, it’s essential to start with quality ingredients, maintain a clean fermentation setup, and monitor the flock’s response closely. Adjustments to the fermentation time, feed composition, and serving methods should be made based on observations of the flock’s health and behavior.
