Here are 10 foods you can ferment for your chickens:
1. Layer or grower feed: When you hear about fermented feed, it usually means just that. Your regular feed can be fermented. Take a look at the basic directions here.
2. Scratch grains: Whole, dried grains do very well. Oats, wheat, corn – whatever you feed as scratch grains can be fermented.
3. Conventional supplements: If you add poultry conditioner, flax seeds, kelp, fish meal, or any other supplement to your regular feed, these can also be mixed into your ferment recipe.
4. Sunflower seeds: My chickens love BOSS – black oil sunflower seeds, sold most commonly for wild birds. Soaking and fermenting will soften the shell and make them that much more delectable.
5. Dried alfalfa: Alfalfa is a great green food that you can provide during winter which also has a high amount of protein. You can buy cubes or pellets of alfalfa at feed and pet stores to add to your ferment.
6. Grasses and clovers: Farmers have been creating silage by fermenting grasses for hundreds of years. Clippings of the plants your chickens like best make a great addition to your feed, either fresh or dried. Try dandelion, comfrey, nettles, clover, or chicory.
7. Vegetables and fruit: Your chickens love your bits and pieces fresh or fermented. Toss some to your chickens while fresh and add the rest in well-chopped bits to the ferment to provide a wider nutrient profile. They would love the cores and bruised parts of your apples and the ends of your garlic cloves. (Apple seeds can be poisonous in large amounts, so I usually remove them.)
8. Grains and flours: In my kitchen, I sometimes use flours like ground chickpeas or flax seed meal or cook steel-cut oats or wild rice. When these ingredients get old or I find an old bag with a few scant tablespoons left, these find new life in the ferment.
9. Crushed egg shells: A great calcium supplement from the flock, crushed egg shells are an ideal candidate. The fermentation process will help to break down the shell and make it more digestible. I don’t bake or treat my shells in any way; I just crush them in a cloth with the bottom of a cup and shake them in.
10. Hard-boiled eggs: Shells and all, I toss hard-boiled eggs into the ferment and crush them with a potato masher! I did try adding them raw once, but it made the mix mold rather quickly. But, hands-down, my chickens’ favorite food of all time is fermented hard-boiled eggs. Yum!
