Why Grinding Your Own Flock Feed Makes Sense

Buying pre-bagged commercial crumbles often means paying premium prices for dusty leftovers that have lost their nutritional potency on warehouse shelves. Whole grains lock in vital vitamins, oils, and enzymes within their protective outer hulls until the moment they are cracked. Grinding your own feed allows you to buy grains in bulk from local farmers, slashing feed bills while serving a much fresher product.

A common mistake is throwing whole corn or hard wheat directly into the coop and expecting small birds to digest it efficiently. Without proper milling, much of the nutritional value passes straight through the bird, leading to wasted feed and empty pockets. Processing grains at home ensures maximum nutrient absorption and lets you customize the protein ratios as your chicks grow into laying hens.

Choosing the Right Grind Size for Your Birds

Getting the grind size right is the difference between a thriving flock and a feeder full of wasted dust. Chicks require a fine, uniform crumble to prevent choking and ensure they do not selectively pick out only the tastiest morsels. For mature laying hens, a coarse crack is ideal, as it stimulates the gizzard and slows down digestion for better calcium absorption.

Avoid over-processing grains into a fine flour, which can turn into a sticky, crop-binding paste when mixed with avian saliva. Conversely, leaving pieces too large means smaller flock members will miss out on key nutrients. Aim for a balanced mix of cracked pieces, small grits, and minimal powder to keep the entire flock satisfied and healthy.

Hand Crank Mill – Corona Landers Corn Mill

Manual plate mills are the entry point for homesteaders wanting to process small batches of feed without relying on electricity.

• Throughput: Designed for kitchen-scale batches, meaning processing more than a few pounds at a time will be slow.
• Grain Hardness: Very hard grains like field corn should be run through on a coarse setting first before attempting a finer grind.

This attachment is perfect for suburban backyard keepers with a small flock of 3 to 6 hens who want to supplement their feed with fresh-cracked grains. It is not suitable for homesteaders with larger flocks or those without a compatible stand mixer.

How to Safely Store Freshly Ground Feed

Once the protective hull of a grain is broken, the clock starts ticking on its nutritional value. The natural oils exposed to the air begin to oxidize, which can lead to rancidity and a rapid loss of essential vitamins, particularly Vitamin E. To prevent this, only grind what your flock can consume within one to two weeks.

Store your freshly ground feed in airtight, food-grade containers kept in a cool, dark, and dry environment. Metal bins with tight-fitting lids are excellent for keeping out moisture and pests like mice and weevils, which are highly attracted to the sweet aroma of freshly cracked grain. Avoid storing feed directly on concrete floors, as moisture can seep through the container bottom and encourage mold growth.

Get into the habit of smelling the feed before filling your feeders; fresh feed should smell sweet and earthy, while rancid feed will have a sour, paint-like odor. If you notice any clumping, dampness, or off-smells, discard the batch immediately to prevent mycotoxin poisoning in your birds.

Balancing Your Flock Diet with Whole Grains

While grinding your own grains offers incredible freshness, chickens cannot thrive on corn and wheat alone. A balanced flock diet requires a careful mix of proteins, carbohydrates, fats, vitamins, and minerals. Grains typically provide the energy component of the diet, but must be supplemented with protein sources like field peas, fish meal, or black soldier fly larvae to meet the 16% to 18% protein requirement for laying hens.

Do not forget to provide free-choice calcium (such as oyster shell) and insoluble grit alongside your custom-ground feed. Because home-ground feed lacks the uniform pelleting of commercial feeds, birds will naturally seek out the grit needed to grind down the coarser particles in their gizzards. This separation of feed and mineral supplements allows each bird to self-regulate based on their individual laying cycle.

Start by replacing a small percentage of your commercial feed with your custom-ground mix, gradually increasing the ratio over two weeks. This transition period allows the birds’ digestive tracts and gizzards to adapt to the new, more textured feed without causing digestive upset or a drop in egg production.

Taking control of your flock’s feed production is a rewarding step toward true homestead self-sufficiency. By selecting the right mill for your scale and mastering the grind, you ensure your birds receive the freshest, most nutrient-dense diet possible. Your extra effort will be rewarded with healthier birds, brighter yolks, and a deeper connection to the daily rhythms of your farm.
