Fermented chicken feed is gaining popularity, and it’s something I like to incorporate on our homestead.


It’s not for everyone, and I certainly have readers that are shy about fermenting anything. It’s understandable, but chicken feed is especially easy to ferment correctly.

Although you might be a little wary (I was once too!), if you ferment for only a brief period of time, you’re more likely to help your hens than harm them.


Obviously, when it comes to chickens, providing clean, fresh food – free of mold – is necessary.

But here’s a reality check:


Particularly if you allow your chickens to free range, they will go after some gnarly food we wouldn’t dream of touching.


Feed you’ve fermented for 48 hours is much more beneficial than that old piece of something unidentifiable that they’re now cooing and clucking over.


That being said, how can you get started fermenting chicken feed?


Worried fermented chicken feed isn't worth the trouble? In fact, it's one of the most beneficial things you can do for your flock! Here's how and why! From FrugalChicken


You can ferment any feed


Organic, not organic, homemade or store bought, the method to ferment your chicken feed is the same.


You can even ferment vegetable and fruit scraps for your chickens! (If you’re making apple cider vinegar, consider tossing the scraps to your flock!)


How to ferment chicken feed


Simply create a daily ration as normal, but instead of feeding it right away, submerge it under water in a clean bucket for 24 to 48 hours. 


Cover the bucket with a cloth or a top in order to keep unwanted stuff out. 
After 24-48 hours, you’ll notice the feed has changed in consistency (what it actually looks like will vary depending on what you’re fermenting).


You might notice a film on top or some cloudy looking material in the bucket – as long as it smells and looks okay, that’s the good bacteria doing it’s job.


With anything fermenting, let your nose and eyes be your guide – if it looks or smells rotten, or if you see black mold, dump it. It’s not worth the risk. 


White or cloudy material should be okay.


If you’re just starting out and not sure about fermented chicken feed, 24 hours might work for you, but feed fermented for 48 hours will yield better results, according to studies.


If you use my organic homemade chicken feed recipe, you can even ferment the seeds for 48 hours before feeding them – the fodder seeds will still sprout under water.


So all this begs the question…


Why bother fermenting chicken feed?


Fermented feed has been proven to more beneficial than dry feed in several studies performed on laying hens.


As the water creates an anaerobic (without oxygen) environment, beneficial bacteria will start to break down the feed. 


As this natural process occurs, it maximizes the nutritional content, making the nutrients more bioavailable, and increases the amount of good bacteria, such as Lactobacilli.


This is the same stuff you see in probiotics for pretty much any species, from humans to chickens to horses.


A study performed by Ghent University in Belgium found that chicks fed a ration fermented for 48 hours were healthier than chickens that were fed a normal dry ration.


In addition, the chickens fed fermented feed were healthier, required less feed, and were more efficient with their feed.


In other words, they were healthier and larger, all while needing less to eat. Pretty nifty, huh?


But it gets better.


A second study performed in Denmark in 2009 showed that laying hens fed fermented chicken feed not only performed better and required less feed, but they showed signs of increased intestinal health.


The same study found that a natural barrier had been formed, protecting the chicken from common pathogens, such as E. coli, Salmonella, and Campylobacter (all of which can be spread to humans.)




Some things to think about


The study performed in Denmark also noticed that because the fermented feed was wet, it caused some behavioral issues.


They saw hens becoming more aggressive, losing interest in their food, and laying later (although it didn’t effect the total amount of eggs laid).


The first thing to remember is these were hens were not a backyard flock, and were in a different environment than homestead chickens.

There is much less competition between backyard hens when it comes to feed, especially if you provide multiple feed stations.


While I personally have noticed my hens occasionally will lose interested in their fermented feed, I’ve not noticed them acting any different.


In addition, the researchers concluded the aggressiveness was tied to the consistency of the wet food, rather than the probiotics.


Fermented feed can get mushy, especially if you use grain. In addition, chickens can be messy eaters, and might toss their feed everywhere – and mushy feed gets ground into dirt much easier.

One way to avoid this is incorporating other goodies into the feed, such as meal worms or table scraps, or even dry feed to provide texture if you find your flock avoiding their fermented feed.
