6 Best Poultry Feeds for Mixed Flocks

Keeping a mixed flock of chickens, ducks, and maybe a few turkeys is one of the great joys of hobby farming, but feeding them can be a real chore. A good all-flock crumble simplifies everything, letting you fill every feeder from the same bag. After years of trial and error, a few brands consistently rise to the top for keeping a diverse flock healthy and productive.

Why a Good All-Flock Crumble is Essential

Trying to manage separate feeds for different species is a fast track to frustration. You’ll have chickens eating high-protein turkey starter, ducks getting into medicated chick feed (which can be toxic to them), and a mess of half-empty bags cluttering your feed room. It’s inefficient and creates unnecessary risk.

An all-flock or flock-raiser formula is designed as a universal baseline. It provides balanced nutrition that is safe for a variety of poultry at different life stages. The goal is simplification—one feed that meets the fundamental needs of everyone, from a growing pullet to a laying duck, freeing up your time and mental energy for other farm tasks.

Purina Flock Raiser: The Time-Tested Classic

When in doubt, you can’t go wrong with Purina Flock Raiser. This is the feed many of us started with, and for good reason. It’s a consistent, reliable product with a 20% protein level that supports growth in young birds and provides enough fuel for adult layers, especially waterfowl.

The biggest advantage of Flock Raiser is its ubiquity. You can find it at nearly any feed store or Tractor Supply across the country, ensuring you never have to make a sudden, stressful feed switch. It’s a no-frills, high-quality crumble that simply works, making it a benchmark against which all other all-flock feeds are measured.

Nutrena NatureWise: For Healthy, Hardy Birds

Nutrena’s NatureWise line is for the farmer who wants to invest a little more in preventative health. This feed goes beyond basic nutrition, incorporating prebiotics, probiotics, and essential oils to support immune function and digestive health. If you’ve struggled with stressed birds or want to give your flock an extra edge, this is a fantastic choice.

Typically formulated at 18% protein, it’s an ideal maintenance ration for a mature mixed flock. While it’s perfect for adult chickens and ducks, keep in mind that you may need to supplement with a higher-protein feed for very young turkeys or meat birds. It’s a trade-off: you get superior gut health support in exchange for a slightly less aggressive growth formula.

DuMOR All Flock: The Practical, Affordable Pick

Let’s be practical: feed is one of the biggest recurring costs on a small farm. DuMOR, Tractor Supply’s house brand, is the undisputed champion of affordability. It’s a straightforward, 20% protein crumble that provides solid nutrition without the premium price tag.

You won’t find fancy additives like essential oils or specialized probiotics here. What you get is a dependable feed that covers all the nutritional bases for chickens, ducks, geese, and turkeys. For the farmer on a tight budget or someone running a larger flock where costs add up fast, DuMOR is a smart, workhorse solution that gets the job done.

Manna Pro All Flock: Probiotics for Gut Health

Manna Pro has carved out a niche by focusing heavily on digestive wellness. Their All Flock crumble is fortified with probiotics to help establish and maintain healthy gut flora. This is particularly useful for young birds or flocks that have experienced stress, leading to issues like pasty butt or loose droppings.

With an 18% protein formula, it’s another excellent choice for a maintenance feed. Manna Pro is also reliably non-medicated, which is a critical factor if you have ducks or geese in your flock, as they should never have medicated feed. It strikes a great balance between advanced gut support and a reasonable price point.

Kalmbach 18% All-Purpose: The Balanced Blend

Kalmbach is a brand that has earned a lot of trust for its focus on high-quality ingredients and consistent formulas. Their 18% All-Purpose crumble is a perfect example of a well-balanced feed designed for the long-term health of a mature, mixed flock. It provides everything they need without pushing for maximum growth.

Like some of its competitors, Kalmbach includes its own proprietary blend of prebiotics, probiotics, and enzymes to aid digestion and nutrient absorption. It’s a premium feed that reflects a commitment to flock wellness, making it a favorite for farmers who are willing to pay a bit more for peace of mind and observable results in their birds’ feathering and energy levels.

Scratch and Peck Grower: The Top Organic Choice

For those committed to an organic, non-GMO, and soy-free operation, Scratch and Peck is the gold standard. This isn’t your typical crumble; it’s often a blend of whole organic grains that you can feed as-is or, ideally, ferment to unlock more nutrients and improve digestibility. It’s a fundamentally different approach to poultry nutrition.

This choice comes with significant trade-offs. The cost is considerably higher, and it requires more labor if you choose to ferment. However, for hobby farmers whose primary goal is producing the cleanest, most natural food for their own family, the extra expense and effort are a worthy investment. It’s a philosophy as much as it is a feed.

Choosing the Right Crumble for Your Mixed Flock

The "best" all-flock feed doesn’t exist. The right feed is the one that best matches your specific situation. Before you buy a bag, consider these points:

• Flock Composition: Do you have turkeys or meat birds that need higher protein (20%+) for rapid growth? Or is it mostly adult chickens and ducks who will thrive on an 18% maintenance feed?
• Your Budget: Be realistic about what you can afford long-term. A basic, affordable feed like DuMOR is far better than constantly switching between premium brands whenever money is tight.
• Your Goals: Are you raising birds for meat, eggs, or just for enjoyment? Are you committed to an organic philosophy? Your answer will narrow the choices significantly.

Ultimately, the decision comes down to a simple framework. For young, fast-growing flocks, a 20% protein crumble like Purina or DuMOR is a safe bet. For stable, mature flocks, an 18% formula with added health benefits from Nutrena or Kalmbach is an excellent investment. And if your values dictate an organic path, Scratch and Peck is your clear choice.

The right all-flock crumble simplifies your daily chores and is a cornerstone of good animal husbandry. Choose a quality brand that fits your flock’s needs and your budget, and you’ll be rewarded with healthy, active birds. Spend less time worrying in the feed aisle and more time enjoying your flock.

Frequently Asked Questions (FAQs)

What is an all-flock poultry feed?

An all-flock poultry feed is a multi-species ration formulated with moderate protein and low calcium to safely nourish chickens, ducks, geese, turkeys, and gamebirds together. These formulas typically contain 16% to 20% crude protein, matching the baseline nutritional needs of non-laying birds and mature waterfowl. Because excess dietary calcium damages the kidneys of non-layers, all-flock rations maintain calcium levels around 1% to 1.5%. Flocks with laying hens require free-choice oyster shell offered in a separate dish to supply eggshell-building minerals.

What does unmedicated mixed flock feed mean for backyard birds?

Unmedicated mixed flock feed is poultry feed made without coccidiostats or antibiotics, making it safe for mixed waterfowl and poultry. Medications like amprolium are common in chick starters, but ducklings and geese consume much more water and feed by weight, risking accidental overdoses with medicated blends. An unmedicated formula prevents toxicity issues across mixed waterfowl and chickens. Keep brooders clean and dry to help young birds develop natural immunity against coccidiosis without pharmaceutical feed additives.

How do I feed calcium to egg layers in a mixed flock?

Backyard keepers should offer coarse oyster shell or crushed limestone in a separate, free-choice hopper mounted away from the main mixed-flock feeder. Laying hens intuitively seek out the supplemental mineral to produce firm eggshells, needing about 4 to 5 grams of calcium daily. Meanwhile, drakes, roosters, and growing juveniles naturally ignore the grit dish because their bodies do not crave it. Never mix calcium directly into the shared feed bin, as forced calcium consumption leads to kidney failure and visceral gout in non-layers.

How do I switch mixed poultry flocks over to a new feed brand?

Transition a mixed flock to new feed by blending the old and new feeds together gradually over a period of 7 to 10 days. Start with 75% old feed and 25% new feed for three days, then shift to a 50-50 mix for the next three days. Finish with 25% old feed and 75% new feed before serving the new formula exclusively on day ten. This measured schedule protects sensitive avian digestive tracts from upset and prevents picky eaters from going off feed.

Which is better for mixed flocks: all-flock pellets or crumble?

All-flock crumbles are generally better for mixed flocks containing waterfowl and smaller bantam breeds because the smaller particle size is easier for varied beak shapes to swallow. Pellets reduce waste around standard chicken feeders, but ducks often choke on large pellets or drop them into their drinking troughs, creating soupy waste. Crumbles break down quickly in water and suit diverse bird sizes from silkies to broad-breasted turkeys. Choose crumbles if your coop houses different species, or use mini-pellets if wind-blown feed dust is a problem in outdoor runs.

How much mixed flock poultry feed does an average bird eat per day?

Adult standard chickens consume about one-quarter pound (115 grams) of mixed flock poultry feed per day, while mature ducks eat approximately one-third to one-half pound. Daily intake increases in winter by 15% to 25% as birds burn extra calories to maintain body heat, and it drops during extreme summer heat. Free-ranging birds that forage for insects, weeds, and seeds often reduce their commercial feed intake by up to 20%. Budget roughly 25 to 30 pounds of feed per standard chicken or duck each month.

What happens if roosters or drakes accidentally eat high-calcium layer feed?

Non-laying birds that eat layer feed suffer from excess blood calcium, which damages their kidneys and often leads to lethal visceral gout or kidney stones. Standard layer diets contain 3.5% to 4.5% calcium, an amount designed strictly for daily eggshell production. Because roosters, drakes, and wethers only require roughly 1% calcium, their renal systems cannot excrete the massive surplus over months of feeding. If non-layers accidentally eat layer feed for a few days, switch them immediately to an all-flock ration with plenty of fresh water to flush the system.

Is all-flock poultry feed safe for ducklings alongside baby chicks?

Commercial all-flock starter-grower feed is safe for brooding ducklings and baby chicks together, provided the formula contains adequate niacin for waterfowl development. Ducklings require roughly 55 to 70 milligrams of niacin per kilogram of feed to prevent crippled legs and bowed joints, whereas chick starters often contain less. Verify the guaranteed analysis label on the feed bag lists sufficient niacin, or supplement each gallon of brooder water with liquid vitamin B complex. Ensure the feed is unmedicated and crushed to a small crumble size so day-old birds can swallow safely.
