6 Best Grain Mill Replacement Burrs For Chickens

You hear the familiar crunch of your hand-crank grain mill, but something’s off. The cracked corn coming out looks more like dust and uneven chunks than the consistent feed your flock is used to. Worn-out burrs don’t just make grinding harder; they create feed that’s less digestible and leads to more waste. Choosing the right replacement burrs is a small decision that has a big impact on your feed bill and the health of your chickens.

Choosing Burrs: Steel vs. Stone for Cracked Corn

The first and most important decision is steel versus stone. For chicken feed, this is a straightforward choice. Steel burrs are what you want for cracking corn and other grains for poultry. They are durable, handle the oils in corn without gumming up, and excel at producing the coarse, cracked texture chickens need.

Stone burrs, on the other hand, are designed to make fine flour for baking. This fine powder is not good for chickens. It can lead to respiratory issues as they peck at it, and can cause a condition called "pasty beak" in chicks where feed gets stuck to their beaks. Stone burrs are also more fragile and can be damaged by an unnoticed pebble in your grain.

So, unless you plan to use your mill primarily for making bread flour for your own kitchen, stick with steel. They are more robust, better suited for the task, and will last longer when processing hundreds of pounds of animal feed. It’s about using the right tool for the job.

Country Living Mill Steel Burrs for Coarse Feed

If you own a Country Living Mill, you already know it’s a serious piece of equipment built to last a lifetime. The replacement grinding burrs are no different. They are machined from high-carbon steel, designed for precision and incredible durability. These aren’t flimsy plates; they are substantial components meant for heavy use.

The key benefit here is consistency. When you set the Country Living Mill for a coarse crack, you get exactly that, batch after batch. This means less dust, less waste, and a feed product that your chickens can easily consume. This level of consistency is what you pay for.

The tradeoff is cost. These burrs are an investment, just like the mill itself. For a farmer with a small backyard flock of six birds, it’s likely overkill. But if you’re managing a flock of 30 or more and processing all your own grain, the reliability and long-term savings from less feed waste make these burrs a very logical choice.

Wonder Junior Auger & Stone Heads for Versatility

The Wonder Junior Mill occupies a unique space because it’s designed for versatility. It’s the mill for the homesteader who wants to do it all—crack corn for the chickens, grind oily seeds for pressing, and make fine flour for bread. This flexibility comes from its interchangeable burr sets.

For chicken feed, you’ll want the steel auger heads. They function just like traditional steel burrs, easily cracking hard corn and other grains into a coarse feed. They are tough and handle the demands of animal feed production well. The stone heads are included for when you want to shift gears and produce fine flour for your kitchen.

This is the perfect system for someone who values multi-functionality in their tools. Instead of buying a separate mill for the kitchen and the barn, you can do both with one machine. The key is understanding which burr set to use for which task. Using the stone heads for oily corn will only lead to frustration and clogged burrs.

C.S. Bell No. 60 Grinding Burr Set Durability

You often find C.S. Bell grinders in old barns or feed stores, and for good reason: they are nearly indestructible cast-iron workhorses. These mills were never intended for fine pastry flour; they were built to process large volumes of animal feed, day in and day out. The replacement burrs for a model like the No. 60 reflect this heritage.

These grinding burrs are massive, heavy, and made to endure. They produce a uniform, coarse product that is ideal for any livestock, including chickens. There are no delicate parts or complex adjustments. You bolt them in, set your grind, and get to work.

Finding a vintage C.S. Bell mill can be a score for a serious hobby farmer. Knowing that high-quality replacement burrs are still available makes it a viable long-term solution for your feed needs. This isn’t about fancy features; it’s about raw, reliable grinding power that will outlast you.

Victoria/Corona Mill Plates for Budget Grinding

Almost everyone starts with a Corona-style mill. They are inexpensive, widely available, and a great entry point into grinding your own feed. The replacement grinding plates for these mills, often sold under the Victoria or Corona brand, are just as accessible.

These plates are typically made of tin-coated cast iron. They will absolutely crack corn for your chickens, but you have to accept their limitations. The grind can be inconsistent, with a mix of fine dust and larger, un-cracked kernels. They also wear down relatively quickly with heavy use.

Think of these as a consumable part. The low cost of replacement plates makes them a practical choice for someone with a handful of birds or who is just testing the waters of home-ground feed. You might go through a set every year or two, but the initial investment is minimal. It’s a perfectly valid tradeoff between cost and performance.

KitchenAid Grain Mill Attachment for Small Flocks

For the homesteader who values efficiency and already has a well-equipped kitchen, the KitchenAid Grain Mill attachment is a surprisingly capable option. It uses all-steel burrs and mounts directly to the hub of any KitchenAid stand mixer, saving you space and the effort of hand-cranking.

This setup is ideal for small-flock owners. If you have a dozen or fewer chickens, grinding a few pounds of corn or wheat once a week is well within its capabilities. It produces a consistent cracked grain without much fuss.

The critical limitation is scale. This is not a tool for processing a 50-pound sack of corn in one go. Doing so will put a tremendous strain on your mixer’s motor and likely cause it to overheat. But for small, regular batches, it’s an elegant solution that leverages a tool you may already own. When the burrs wear, you typically replace the entire attachment.

Lehman’s Best Hand Grinder Replacement Burrs

Lehman’s has built its reputation on providing durable, non-electric tools for a self-sufficient lifestyle, and their hand grinder is a perfect example. It sits squarely between the budget Corona mills and the premium Country Living. The replacement burrs for this grinder reflect that middle-ground philosophy.

Made from quality steel, these burrs offer a significant upgrade in durability and grind consistency over the basic tin-coated plates. They hold their setting better, produce less dust, and will last much longer under regular use. This means more of your grain ends up as usable feed for your flock.

This is the choice for the hobby farmer who is committed to grinding their own feed by hand but wants a tool that feels solid and reliable without the premium price tag. It’s a practical investment in quality that pays off in better feed and less frustration over time.

Burr Maintenance: Cleaning and Seasoning Guide

Your grinding burrs will only last if you take care of them. The biggest enemy of steel and iron burrs is rust, and the biggest cause is improper cleaning. Never use water to clean your burrs. It will cause them to rust almost immediately, seizing them up and ruining the grinding surfaces.

The correct way to clean burrs is with a stiff, dry brush. A nylon bristle brush or an old toothbrush works perfectly. Use it to scrub away any caked-on flour or grain fragments after each use. For stubborn bits, a wooden skewer or a toothpick can help dislodge them.

For long-term storage, especially in a humid barn or basement, it’s wise to season your burrs. After brushing them clean, wipe a very thin layer of food-grade oil (like coconut oil or even just vegetable oil) onto all surfaces. Then, use a clean, dry cloth to wipe off as much of the excess as you can. This leaves a microscopic protective layer that prevents rust from forming.

Finally, remember that new burrs often have a coating from the manufacturing process. Before using them for feed, run a cup of cheap rice or feed corn through them and discard the output. This "break-in" grind cleans off any residue and ensures your first batch of chicken feed is pure.

Ultimately, the best replacement burrs are the ones that fit the scale of your flock, your budget, and the mill you already own. Whether you’re using a budget-friendly Corona or a lifetime-quality Country Living, maintaining sharp, clean burrs turns whole grains into high-quality feed. It’s a small detail that supports the bigger goal: raising healthy, productive chickens in a more self-sufficient way.
