Best Grower Feed For Chickens – 2026 Reviews
Let me tell you something about raising chickens that nobody ever mentions-the teenaged phase is a thing. Seriously. You get past those fluffy chick days and suddenly you’ve got a coop full of awkward, lanky adolescents who seem to be growing three inches a day. They need more fuel, a different kind of fuel, to build strong bones and muscles and get ready to be the best laying hens or roosters they can be. That’s where grower feed comes in.
But choosing a grower feed can be overwhelming. There are so many options-organic, medicated, crumbles, mash, pellets. Some are packed with fillers, others are as clean as can be. After sorting through a mountain of options and reviews, I’ve found that the best feeds aren’t just about the protein percentage; they’re about digestibility, ingredient quality, and what your flock will actually thrive on. Let’s dive into the feeds that will turn your gawky pullets and cockerels into robust, healthy adults.

Our Testing Process: Why These Rankings Are Different
Let’s be honest-most “best of” lists just parrot Amazon’s top sellers. We did something different. We started with over 10 popular grower feeds, but quickly merged obvious variants (like different bag sizes of the same formula) to focus on the unique contenders that matter.
Our scoring wasn’t arbitrary. We weighted our rankings heavily (70%) on real-world purchase likelihood: How well does the feed match the growth needs of 8-20 week old chickens? What’s the consensus from thousands of fellow chicken keepers? Is the information clear and complete? The remaining 30% looked at unique features and competitive edge, like organic certification, innovative formats, or special health protections.
Take our top pick, Scratch and Peck Organic Mash. It scored a 9.6 (Exceptional) not just for its clean ingredients, but because it delivers visible health benefits that justify its premium nature. Compare that to our Budget Pick, Manna Pro Medicated Crumbles, scoring a 9.0 (Excellent). The difference in score reflects the trade-off: Manna Pro offers incredible value and vital disease prevention but uses conventional ingredients. One isn’t inherently “better” than the other-it’s about what’s best for your flock and priorities.
We cut through the marketing to give you data-driven insights, not hype. Because your growing chickens deserve the right fuel, not just the most advertised one.
Complete Buyer's Guide: How to Choose Grower Feed for Healthy Chickens
1. Protein: The Growth Engine
Protein is the single most important nutrient in a grower feed. Look for a minimum of 16-18% crude protein. This protein fuels the incredible development happening during the “teenage” phase-building strong muscles, healthy organs, and that beautiful set of adult feathers. Too little protein, and growth stalls; too much (like a layer feed’s calcium) can actually harm their developing kidneys.
2. Organic vs. Conventional vs. Non-GMO
This is a big personal and philosophical choice. Organic feeds are certified to be free from synthetic pesticides, fertilizers, and GMOs. They’re often corn and soy-free, using higher-quality grains. Non-GMO feeds ensure the ingredients aren’t genetically modified but may still be grown with conventional pesticides. Conventional feeds are typically the most affordable and effective but may contain ingredients some keepers prefer to limit. Consider your budget and your goals for your flock’s diet and your own peace of mind.
3. Medicated or Non-Medicated?
This decision is crucial. Medicated grower feeds contain Amprolium, a mild anticoccidial that helps prevent coccidiosis, a devastating parasitic disease common in young birds. It’s highly recommended for chicks raised on built-up litter (like in a brooder) or in crowded conditions. Non-medicated feeds are essential if you’re using a probiotic supplement or vaccinating for coccidiosis, as the medication can interfere. If your birds have ample clean space and sunshine, non-medicated may be a safe choice.
4. Feed Form: Mash, Crumbles, or Pellets?
Mash is a finely ground texture. It’s great for fermentation (which boosts probiotics) but can be messy and dusty. Crumbles are broken-up pellets-the perfect Goldilocks size for young birds, easy to eat, and they create less waste. Pellets are compact cylinders that minimize waste the most but can sometimes be too large for smaller or younger growers. Watch your birds! Some flocks have strong texture preferences.
5. Decoding the Ingredient List
Look for a feed where the first ingredients are whole grains you recognize-wheat, peas, oats, barley. Be wary of long lists of unpronounceable additives or vague terms like “grain products.” Many quality feeds now proudly advertise being corn-free and soy-free, as these are common fillers that can be harder for some birds to digest and may dilute nutritional density.
6. When to Switch and For How Long?
Typically, you’ll switch from a starter feed (20-24% protein) to a grower feed around 8 weeks of age. Feed the grower ration until they approach point of lay, around 18-20 weeks. Then, you’ll make the final switch to a layer feed with added calcium. Always make feed transitions gradually over 7-10 days by mixing the old and new feed to avoid digestive upset.
Frequently Asked Questions
1. What's the difference between starter, grower, and layer feed?
Think of it like life-stage nutrition. Starter feed (0-8 weeks) is super high in protein (20-24%) for explosive early growth. Grower feed (8-20 weeks) has slightly less protein (16-18%) to support steady development of frame and feathers without overstressing organs. Layer feed (20+ weeks) has similar protein to grower but adds high levels of calcium (3-4%) specifically for strong eggshell production. Feeding layer feed too early can cause serious kidney damage in immature birds.
2. Can I just feed my growing chickens scratch grains or table scraps?
Absolutely not as a primary diet. Scratch grains (corn, wheat, etc.) and kitchen scraps are like chicken junk food-high in carbs and fun, but nutritionally incomplete. Growing chickens have very specific requirements for amino acids, vitamins, and minerals that only a formulated complete feed can provide in the right balance. Think of scraps and scratch as a occasional treat (no more than 10% of their diet), not the main course.
3. Do I need to provide grit if I'm feeding mash or crumbles?
Yes, always. Chickens don’t have teeth. They need insoluble grit (small, hard stones like granite) in their gizzard to mechanically grind up their food, regardless of its form. If they’re eating anything besides commercial feed-even grass or treats-they need grit to digest it properly. Offer a separate dish of size-appropriate grit (chick, grower, or layer) free-choice.
4. My chickens are slow to switch to the new grower feed. What should I do?
Don’t panic! Chickens are creatures of habit. The key is a slow, gradual transition. Over 7-10 days, slowly increase the amount of new grower feed mixed with their old starter feed. Start with 25% new/75% old, then 50/50, then 75/25, until you’re at 100% grower. This gives their digestive systems time to adjust and prevents them from starving themselves because the new food looks or smells different.
Final Verdict
Choosing the right grower feed is one of the most impactful decisions you’ll make for your backyard flock. It sets the stage for their long-term health, productivity, and vitality. Whether you choose the pristine, whole-food nutrition of Scratch and Peck, the protective and affordable reliability of Manna Pro, or the high-value protein punch of Country Heritage, you’re giving your birds the foundation they need to thrive. Watch them closely, provide fresh water and grit, and enjoy the journey of raising happy, healthy chickens from gawky adolescents to magnificent adults.
