Lately I have been reading about the benefits of fermented chicken feed but there is so much to know!  Get the basics answered with The Hows & Whys of Fermented Chicken Feed

What is fermented food and why should you add it to your chicken’s (or your) diet?

Fermentation is the chemical breakdown of food by natural bacteria, yeast or microorganisms.  They feed on the sugars and starch in the food.  Some foods that are typically fermented include beer, pickles, bread, cheese, yogurt, sauerkraut and so many more.

Fermenting helps preserve food and adds beneficial enzymes, vitamins B, C and K, folic acid and various strains of probiotics. Because fermented foods have already been partially broken down, they are easily digestible & helpful for absorbing nutrients. Fermented foods & drinks add beneficial bacteria to your digestive system.  This helps aid in nutrient absorption, not just in the fermented food you are eating, but all the food you eat as the good bacteria lingers in your gut.

 All those vitamins & nutrients can help keep us (and our chickens) healthier and ward off diseases.  It can boost intestinal health by forming a barrier to pathogens like E. coli and Salmonella.  

Best of all fermenting chicken feed is super inexpensive and can help stretch your feed budget.  There will be less wasted feed.  With dry feed, chickens tend to scratch it around and make a big mess.  With a fermented mash, they will gobble up every bit!  With enhanced digestion, your hens will stay fuller longer, meaning they will eat less, again saving you money.  In your laying hens you will notice a larger, tastier yolk, stronger shells & an all around healthier flock.  Sold yet?  Let me give you one final reason – it is ridiculously easy!

But how do you ferment chicken food?

Fermenting chicken feed requires just a few things – a large jar with lid, filtered water, chicken feed (you can use crumbles, pellets, even scratch) and time.

The hows and whys of fermented chicken feed

First, you have to decide how much feed you are going to want to have fermenting so you can choose the appropriate size container.  If you want this to be their only source of feed, you will want to plan on about 1/2 cup per chicken per day.

Good container choices are large Mason jars or a big 5 gallon bucket if you have a large flock, but you could use any plastic or glass jar with a lid.  Avoid using a metal container as the high acid of the fermented feed can interact with the metal and contaminate your feed.

I only feed them fermented feed as an occasional treat so I just use a large mason jar.  Do what you can with the space you have.  If you have a nice warm (at least room temperature) spot where you can keep several jars or buckets you can get a great fermentation rotation going where you have lots of jars in various states of fermentation so your flock can exclusively eat fermented feed.

Add your feed to a clean jar, only fill it about one third to one half full to allow room for the feed to expand (I filled this one a bit too much. Don’t panic if it starts to over expand.  Just scoop some out and feed it to the flock early)

Add water so that it covers all the feed plus a couple inches.  You will find on the first day you will have to add water throughout the day (and possibly scoop out some feed if it expands too much).  As the feed soaks up the water, the water line will get lower and it is important that all the feed stays submerged so bad bacteria and mold will not grow.  It’s best to not use tap water as most towns add chlorine to prevent bacteria growth (both good & bad).  You don’t want to use something that will kill the good bacteria.

Put the lid on and let it sit in a room temperature place for 3-4 days.  Once or twice a day open the jar up to off gas it and give it a stir.  Add water if needed to be sure the feed stays submerged. You can feed your flock the fermented feed at any point, but the beneficial nutrients will peak around day 3 or 4.

Properly fermented feed will be bubbly and smell tangy and slightly sour (similar to yogurt).  It should NOT smell rotten .  Fermented feed that smells rotten has bad bacteria or possibly mold growing in it.  If you made sure to keep the feed totally submerged and have not had it soaking for more than 4-5 days it is pretty unlikely your feed will have gone bad.

Scoop out the fermented feed and put it in a shallow dish for the chickens and watch them go crazy!  In the winter, pop the fermented mash into the microwave for a warm treat (be sure to thoroughly stir and test the temperature before feeding)

    We live in the country so, we have well water. Can I use well water or do I need to buy filtered water to make fermented chicken feed?

    1. I don’t have a lot of experience with well water, but do you add chemicals to the well that might kill bacteria? This is the main issue with using tap water, treated water will kill bacteria – both the good & the bad. If your well water is untreated, my guess is it would be fine for fermentation

    2. You can use well water. It’s the best and won’t harm your fermented food in any way.

    Opps and i thew away lots of feed because it rain in the bucket all day and night

    1. Oh no! You had a bit of natural fermenting going on!

    2. Jocelyn says:

      Happened to me too, with scratch. It started sprouting, and smelled a bit like vinegar. The chickens liked it and suffered no ill effects.

  3. Mindy Griggs says:

    What if I did use tap water?? Should I throw it out and start over???? I forgot to use distilled water.

    1. You can let it go and see what happens, it’s not poisonous or anything. The problem with tap water is it usually treated to prevent bacteria growing it and that can also sometime kill the good bacteria you are trying to cultivate.

  4. Alegria Garcia says:

    How often should you feed this to your flock?

    1. I feed it as a treat a couple times per week, but you can do this daily if you want

  5. Suzanne Turo says:

    Do the ducks like the fermented feed? I’m currently feeding mine new country organic soy free feed and they go thru about 75# a month, and they free range all day. Would like to stretch it if I can.

    1. Ducks LOVE fermented feed (maybe even more than chickens) because it’s easier for them to eat

    I am definitely going to ferment food for my chickens. I have been reading about it and can’t find anything near it’s beneficial properties. My only concern is I have absolutely no space to even store single a jar inside my home, it’s that small. However I do have a nice garage space. Could I keep it there as long as I followed all necessary steps in the procedure? I live in zone 8/9 in Texas and it can get quite hot but the garage will lower the out side temp by 10-15 degrees so probably looking at an average of 80 degrees or so. Is that just to hot?

    1. I definitely don’t live where it’s very hot for extended periods of time so I don’t have any first hand knowledge of this, but I would think 80 degrees or so should be fine. I’ve fermented feed in my house in the summer where the temps inside could be mid 70s so that isn’t too far off!

  7. Stevie says:

    How long will the fermented feed last please? Does it need to be stored airtight, or can I just replace the scoop of fermented feed I take out with a scoop of fresh feed?

    1. I don’t usually let the feed go beyond a week or so, so I can’t properly answer that question. You could experiment with a small amount. It should smell sweet and a little yeasty. If it smells rotten, it’s gone bad and should not be fed to your animals. It would probably be better to just have a few jars going at once rather than “feeding” the already fermented feed with new feed

  8. Elisa Hinojosa says:

    Hello! I am a new chicken mom. Can I used a chicken feed that contains yeast in the ingredients for fermentation? Will they get drunk?

    1. That is totally fine – no drunk chickens!
