When your hens scratch eagerly at your feet, they’re trusting you to give them something pure. Not grains sprayed with glyphosate, not soy grown from modified seeds—just real, honest nutrition that turns into golden yolks and glossy feathers. Choosing the right feed can feel overwhelming, but your flock’s health depends on cutting through the marketing noise.

I’m Mo Mahin — the founder and writer behind Furric. I’ve spent months analyzing ingredient lists, cross-referencing veterinary nutrition guidelines, and reading hundreds of flock owner reviews to separate truly clean feeds from greenwashed bags.

After months of research and consulting with poultry nutritionists, I’ve narrowed down the truly best non gmo chicken feed that supports strong eggshells and vibrant feathers.

How To Choose The Best Non Gmo Chicken Feed

Not all bags labeled “natural” meet the strict Non-GMO standard. Look for third-party verification like the Non-GMO Project seal, and check that the protein source—whether grains, legumes, or insects—is clearly traceable. A quality feed will also specify the percentage of protein, calcium, and key amino acids.

Understand Your Flock’s Life Stage

Layer hens need at least 16% protein and extra calcium for shell strength, while chicks require 18–20% protein with medicated or non-medicated options. Starter feeds often skip Non-GMO claims, so always read the fine print. If you’re raising heritage breeds or sensitive birds, choosing a Non-GMO formula can reduce digestive stress and boost immunity.

Look Beyond the Base Grain

Corn and soy are common fillers that are often genetically modified. Many quality Non-GMO layer blends substitute with oats, barley, or sunflower meal. Whole grains also encourage natural foraging behavior. For a protein punch, consider supplementing with dried black soldier fly larvae—they’re naturally Non-GMO and pack more calcium than mealworms.

Best Overall

1. Wholesome Harvest Non-GMO Whole Grain Layer Blend

Non-GMOProbiotic

Backyard chicken keepers are buzzing about this blend—it’s a complete layer mash that skips GMOs entirely. Fortified with oyster shell, flax (for omega‑3s), and probiotics, it’s designed to boost eggshell quality while keeping digestion smooth. The cracked whole grains—corn, soy, wheat, and barley—are all Non-GMO Project verified, so you’re not guessing about what’s inside.

What sets it apart is the inclusion of herbs and essential oils, which some flock owners say helps with respiratory health and natural pest resistance. The 16% protein level meets the needs of most laying hens, and the added calcium means you won’t need separate oyster shell supplements. Reviewers consistently mention how eagerly their birds eat it, often preferring it over standard pellets.

If you want a single-bag solution that covers nutrition, shell strength, and ethical sourcing, this is the feed to start with. It’s slightly pricier than commodity feeds, but the ingredient transparency and flock response make it a worthy investment for health-conscious keepers.

Why we love it

  • Certified Non-GMO whole grains with clear sourcing
  • Includes probiotics for digestive health
  • Omega‑3 from flax supports richer egg yolks

Good to know

2. Prairie’s Choice Non-GMO Backyard Chicken Feed – Layer Formula

Non-GMOGluten-Free

Poultry enthusiasts who prioritize clean labeling often turn to Prairie’s Choice. This 25‑pound layer formula is Non-GMO, antibiotic‑free, non‑medicated, and even gluten‑free—an uncommon trifecta in chicken feed. The 16% protein crumble is designed for hens 16 weeks and older, and it’s grown, milled, and packaged entirely in the USA.

Long-term users report that their hens maintain steady egg production year-round, with noticeably stronger shells. The crumble form makes it easy for birds to eat without waste, and the heavy bag stores well in dry conditions. One flock owner noted that after switching from a major brand, their chickens’ droppings firmed up and feather quality improved within weeks.

If you’re willing to invest a little more per bag for the peace of mind that comes with verified Non-GMO ingredients and strict quality control, Prairie’s Choice delivers consistency that commercial blends often lack. It’s especially well‑suited for small flocks where every egg counts.

Why we love it

  • Triple‑certified: Non-GMO, antibiotic‑free, gluten‑free

3. Grubs Delight 5LB Dried Black Soldier Fly Larvae

Non-GMOHigh Calcium

Hen parents looking for a treat that actually benefits health will appreciate these dried black soldier fly larvae. They pack 45% protein and a remarkable 6% calcium—85 times more calcium than dried mealworms—making them perfect for supporting eggshell strength and helping birds through molting. The larvae are 100% Non-GMO, raised on upcycled pre-consumer food waste, and packed in a resealable bag for freshness.

While this is a supplementary treat rather than a complete feed, many flock owners use it daily as a training tool or foraging scatter. The high calcium content means you can reduce or even eliminate separate oyster shell supplements. Reviewers note that even picky eaters go wild for the grubs, and the sustainable sourcing appeals to eco‑conscious keepers.

For a powerful nutritional boost that encourages natural scratching and pecking behavior, this bag delivers exceptional value. Just remember that treats should make up no more than 10% of your chickens’ total diet—balance it with a quality Non-GMO layer feed.

Why we love it

  • Exceptionally high calcium for shell health
  • Sustainable, Non-GMO, and traceable sourcing
  • Resealable bulk bag lasts for weeks

Good to know

  • Not a complete feed – must be used as a supplement
  • Some birds may need a few days to accept whole larvae
Starter Option

4. Purina Start and Grow Non-Medicated Chick Feed

PrebioticHigh Protein

Raising strong chicks starts with the right nutrition, and this Purina formula delivers 18% protein with added lysine and methionine for proper muscle and skeletal development. It’s a complete, medicated‑free starter that includes prebiotics and probiotics to support digestive and immune health. The crumble form is easy for day‑old chicks to eat and reduces waste.

While Purina doesn’t market this feed as Non-GMO, the ingredient list shows no added antibiotics or growth hormones, and many backyard breeders choose it for its reliable nutritional balance. The added marigold extract helps give young birds bright beaks and plumage as they mature. Owners report that chicks transition smoothly to layer feed when using this starter.

If you’re raising chicks and want a trusted, widely available option, this is a solid choice. Just be aware that it lacks a Non-GMO certification—if that’s a deal‑breaker, look for a certified Non-GMO starter. For a non‑medicated, probiotic‑rich starter, this one stands out in the mainstream market.

Why we love it

  • Balanced 18% protein with essential amino acids
  • Prebiotics and probiotics for digestive health
  • No medications or artificial preservatives

Good to know

  • Not certified Non-GMO
  • Large 25‑lb bag may be heavy for some keepers

5. Purina Layena Layer Hen Feed Crumbles

Marigold ExtractOyster Strong

For budget‑conscious flock owners who still want a well‑balanced layer feed, Purina Layena is a longtime favorite. It’s formulated to deliver strong shells via the Oyster Strong System, and the added marigold extract produces rich, golden‑yellow yolks. The 10‑pound bag is easy to handle and great for small flocks or as a backup when you run out of your main feed.

What it lacks is a Non-GMO certification—Purina uses conventionally grown grains. That said, the formula skips artificial by‑products, preservatives, antibiotics, and growth hormones. Many keepers who don’t require organic or Non-GMO feed still choose it for its consistent quality and availability. The crumble texture reduces dust compared to pellets, and birds accept it readily.

If your priority is a reliable, affordable layer feed and you’re not strict about GMOs, this is a practical choice. For the price, you get proven nutrition that keeps hens laying. But if Non-GMO is non‑negotiable, look at the Wholesome Harvest or Prairie’s Choice options above.

Why we love it

  • Proven egg‑laying support with strong shells
  • Marigold extract for vibrant yolks
  • Affordable and widely available

Good to know

  • Not certified Non-GMO
  • 10‑lb bag has higher cost per pound than larger sizes

Safety & Care Tips

Store Feed Properly to Prevent Mold

Moisture is the enemy of chicken feed. Always keep feed in a cool, dry place, ideally in a metal or heavy‑duty plastic container with a tight lid. Avoid storing bags directly on concrete floors, which can wick moisture. Check feed regularly for musty smells or clumps—mold can cause serious health issues like aflatoxicosis.

Transition Feeds Gradually

Switching to a new Non-GMO feed should happen slowly over 7–10 days. Mix increasing amounts of the new feed with the old each day to avoid digestive upset. Sudden changes can cause chickens to stop eating or develop loose droppings. Observe your flock’s appetite and egg production during the transition.

Balance Treats with Complete Feed

Even the best Non-GMO treats like black soldier fly larvae should not exceed 10% of your flock’s daily intake. Overfeeding treats can lead to calcium imbalance or reduced appetite for complete feed. Use treats as foraging enrichment, not meal replacements.

Check Water and Calcium Separately

Even if your feed contains oyster shell, offer a separate dish of crushed oyster shell free‑choice so hens can self‑regulate calcium intake. Fresh, clean water should be available at all times—dehydration can reduce egg production faster than any feed change.

FAQ

What does Non-GMO certification mean for chicken feed?
Non-GMO certification means the feed’s ingredients (corn, soy, grains) have been verified to come from plants that were not genetically modified. Look for the Non-GMO Project Verified seal or other third‑party certifications. This label also typically indicates that the feed does not contain synthetic pesticides or herbicides used on GMO crops.
Do Non-GMO feeds improve egg taste or yolk color?
While the direct taste difference is minimal, Non-GMO feeds that include ingredients like flaxseed and marigold extract can produce richer yolks and a deeper orange color. Many keepers report that eggs from hens on a Non-GMO diet taste cleaner and fresher, likely due to the absence of artificial additives.
Can I feed Non-GMO layer feed to my ducks?
Yes—most Non-GMO layer blends formulated for chickens also work well for ducks. Ducks have slightly higher protein needs (16–18% for layers), so check the label. The Wholesome Harvest blend explicitly lists ducks as suitable. Always provide extra niacin for ducks, as they require more than chickens.

Final Thoughts: The Verdict

For most flock owners who want a dependable, Non-GMO complete feed that covers all bases, the winner is the Wholesome Harvest Non-GMO Whole Grain Layer Blend because it combines certified Non-GMO grains with probiotics, omega‑3s, and oyster shell for shell strength. If you prefer a crumble with a gluten‑free label and USA‑grown ingredients, grab the Prairie’s Choice Non-GMO Layer Formula. And for boosting calcium and protein during molting or as a high‑value treat, nothing beats the Grubs Delight Black Soldier Fly Larvae.
