Thin, brittle eggshells and a drop in lay rate are the clearest signs your flock’s current ration is missing critical nutrients. The wrong feed leaves hens underperforming, wastes your money on filler grains, and can even lead to health issues like egg binding. Getting the calcium-to-protein ratio right is the single most impactful change you can make for a productive backyard flock.
I’m Mohammad — the founder and writer behind ProteinJug. I’ve spent years analyzing poultry nutrition research and comparing the ingredient decks of commercial layer feeds to understand exactly which formulas deliver measurable improvements in shell thickness, yolk color, and daily yield.
After sifting through dozens of formulations and thousands of keeper reviews, I’ve narrowed it down to the five rations that deserve a spot in your coop. This is your definitive guide to picking the right food for egg laying chickens based on real nutritional specs and flock feedback.
How To Choose The Best Food For Egg Laying Chickens
Not all layer feeds are created equal. A bag from the farm store might claim to be “complete,” but if the calcium level sits below 3.5% or the protein dips under 15%, your hens will struggle to produce strong shells and consistent eggs. Focus on three pillars: protein content, calcium fortification, and ingredient sourcing.
Protein Percentage and Amino Acid Profile
Laying hens need 16–18% crude protein to support daily egg formation. Methionine and lysine are the two essential amino acids that directly impact egg size and albumen quality. If your current feed lacks a guaranteed analysis for these, you may need to supplement with black soldier fly larvae or a high-protein treat to fill the gap.
Calcium and the Oyster Shell Connection
A layer feed should contain 3.5–4.5% calcium. Most premium rations use oyster shell or a proprietary “Oyster Strong” system to provide a slow-release calcium source that hens draw from during shell formation overnight. Without this structural calcium, you get thin shells, cracked eggs, and potentially egg-bound birds.
Feed Form: Pellets, Crumbles, or Mash
Pellets minimize waste because chickens can’t selectively pick out their favorite pieces. Crumbles are easier for younger layers to manage, while mash is the most natural but often leads to higher spillage. For a mixed flock of adult hens, pellets usually offer the best balance of nutrition delivery and low waste.

In‑Depth Reviews
1. Prairie’s Choice Non-GMO Backyard Chicken Feed – Layer Formula, 25lbs
Prairie’s Choice hits the sweet spot for the keeper who wants clean ingredients without hunting down a specialty mill. This crumble is Non-GMO, antibiotic-free, and gluten-free — grown, milled, and bagged in the USA. The 16% protein floor is the baseline for solid egg production, and the crumble form works well for mixed-age flocks that include younger pullets just coming into lay.
Customer reports note a striking improvement in egg size after switching from generic store brands, and several long-term users have stuck with it for over three years. The heavy, resealable bag design keeps the feed fresher than flimsy paper sacks. One keeper observed that hens resumed laying within days after the switch, suggesting the previous feed lacked key nutrients this formula provides.
There is one minor behavioral quirk: some hens will pick around the corn pieces at first. This usually resolves within a week as they adjust to the texture. For a premium, transparently sourced ration that delivers consistent performance, this is the top pick for the discerning flock owner.
Why it’s great
- Non-GMO, antibiotic-free, gluten-free clean label
- Proven to restore laying in hens that stopped producing
- Durable, well-sealed bag for storage
Good to know
- Some hens initially pick out corn pieces
- Premium tier pricing per pound
2. Purina Layena+ | Nutritionally Complete Layer Hen Feed | Omega 3 Formula – 10 Pound Bag
Purina’s Layena+ is the go-to if your goal is to produce eggs with a measurable nutritional edge. The formula is designed to deliver 250 mg of Omega-3 per large egg, which is a real differentiator for keepers who sell eggs or simply want richer yolks for their own table. The Non-GMO vegetarian diet ensures no animal byproducts end up in the ration.
Customers consistently report thick eggshells and dark yellow yolks, which are visual markers of good calcium assimilation and balanced nutrition. Multiple reviewers have set this feed on auto-reorder, citing reliable delivery and product freshness. The pellet form reduces waste significantly compared to crumbles, especially in outdoor feeders where wind can scatter lighter bits.
The main frustration with this product is availability. Several reviews flag that it frequently goes out of stock across sellers, which can disrupt your flock’s routine if you rely on a strict schedule. For keepers who prioritize egg quality and don’t mind occasional stock checks, the nutritional payoff is worth the extra attention.
Why it’s great
- Guaranteed 250mg Omega-3 per egg
- Consistent thick shells and rich yolk color
- Low-waste pellet form
Good to know
- Frequent out-of-stock issues reported
- 10 lb bag may be small for large flocks
3. Classic Flock 10lb Dried Black Soldier Fly Larvae Chicken Feed
Black soldier fly larvae are not a complete feed, but they are the single best supplement you can add to your layer ration for a protein and calcium boost. Classic Flock offers these dried larvae with a soft exoskeleton that makes them easy for hens to digest, and the 10 lb bag provides a cost-effective alternative to pricier boutique brands.
Keepers report that their chickens go absolutely wild for these larvae, which makes them ideal for training, taming, or rewarding hens. The calcium content is naturally higher than mealworms, which supports shell strength without requiring additional oyster shell supplementation. The larvae arrive in a secure box rather than a bag, reducing the risk of crushing during shipping — a common complaint with competing products.
Because this is a treat, not a complete feed, you should limit portions to around 10% of the daily diet to avoid unbalancing the calcium-to-protein ratio of their main ration. For keepers looking to push egg production higher or improve feather condition during molting, this supplement delivers serious results at a fair price.
Why it’s great
- Higher calcium than mealworms for shell support
- Secure box packaging prevents crush damage
- Excellent price per pound for bulk larvae
Good to know
- Not a complete feed; must pair with layer ration
- Should stay under 10% of daily diet
4. Wholesome Harvest Non-GMO Whole Grain Layer Blend 16% – 10lb
Wholesome Harvest takes a different approach by incorporating essential oils, herbs, and oyster shell directly into a whole grain blend of cracked corn, soybeans, wheat, and barley. This granule-form feed is designed for keepers who want a Non-GMO option with extra digestive support from probiotics and higher Omega-3 levels from linseed oil.
Chickens show strong enthusiasm for this blend — multiple reviewers describe their flock going “crazy” at feeding time. The 16% protein level is appropriate for adult layers, and the inclusion of oyster shell means you don’t need to offer a separate calcium source in most cases. The bag size is best suited for small to medium flocks; keepers with over ten birds note the 10 lb bag goes quickly.
The main downside is the cost per pound relative to bulk options. For a keeper running a large flock, the per-bag price adds up fast. However, for small backyard operations that prioritize ingredient transparency and a varied grain profile, this blend simplifies feeding by combining grain, calcium, and herbal supplements in one pour.
Why it’s great
- Whole grain blend with probiotics and herbs
- Oyster shell included for calcium
- Hens show very high palatability response
Good to know
- 10 lb bag is small for larger flocks
- Premium cost per pound
5. Purina Layena Pellets, Chicken Feed for Laying Hens, 25 lbs
The standard Purina Layena pellet is the entry-level champion for keepers who want reliable nutrition without the premium price tag of specialty blends. This 25 lb bag uses Purina’s proprietary Oyster Strong System to deliver structural calcium for thick eggshells, and the pellet form consistently produces less waste than crumbles or mash in outdoor feeders.
Customer feedback is remarkably consistent: hens like the taste, shells come out hard and thick, and the large bag size offers strong value per pound for medium flocks. Multiple buyers mention that switching to this feed reduced cracked eggs noticeably. The pellets hold up well in tube feeders without clogging, and the formula works across mixed flocks that include different chicken breeds.
The trade-off is ingredient transparency. This is a standard commercial formula, not Non-GMO or organic, and it lacks the added Omega-3 or herbal inclusions of the premium options. For the keeper whose priority is a dependable, waste-minimizing feed that keeps hens laying at a reasonable cost, this remains a solid, no-fuss choice.
Why it’s great
- 25 lb bag offers strong value per pound
- Oyster Strong System delivers hard shells
- Pellet form minimizes feeder waste
Good to know
- Standard formula, not Non-GMO or organic
- No added Omega-3 enrichment
