The difference between a flock that barely scrapes by and one that churns out thick-shelled, dark-yolked eggs every morning often comes down to a single decision: what you put in the feeder. Scratch grain is the classic treat, but laying hens have specific calcium and protein demands that a straight corn mix simply cannot meet. The wrong scratch can leave you with thin shells, molting delays, and a lot of wasted feed scattered in the bedding.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent years digging through feed labels, comparing ingredient lists, and analyzing aggregated owner feedback to separate the high-quality blends from the bulk-bin filler that does nothing for egg production.
Whether your goal is richer yolks, stronger shells, or just a treat that keeps your hens active and happy, choosing the right mix matters. This guide breaks down the five best options on the market so you can confidently pick the best chicken scratch for laying hens for your specific backyard flock.
How To Choose The Best Chicken Scratch For Laying Hens
Not all scratch is created equal. A laying hen burns through calcium and protein at a much higher rate than a non-laying bird, so the scratch you pick must complement her layer feed rather than just fill her crop with empty carbs. Below are the three most critical factors to weigh before buying.
Crude Protein Percentage
Laying hens need a minimum of 16% crude protein in their total diet to maintain egg production and feather health. Straight cracked corn sits around 7–9% protein, which can drag down the overall nutritional density of your hen’s daily intake. A scratch blend that includes soybeans, black soldier fly larvae, or other protein-rich ingredients will help your flock maintain steady laying cycles even during molting season.
Calcium and Eggshell Fortification
Thin shells and cracked eggs are almost always a calcium deficiency signal. The ideal scratch for layers includes added oyster shell, limestone, or a high-calcium ingredient like black soldier fly larvae (which delivers up to 85x the calcium of mealworms). If your scratch lacks calcium fortification, you will need to offer a separate oyster shell supplement in a free-choice feeder.
Omega-3 and Grain Diversity
Hens that eat a varied blend of cracked corn, wheat, barley, oats, and flaxseed produce eggs with noticeably darker yolks and higher omega-3 content. A monoculture scratch (pure corn) yields pale yolks and offers no fatty-acid benefit. Look for blends that list at least three grain sources plus flax or linseed for the best egg quality payoff.

In‑Depth Reviews
1. Prairie’s Choice Non-GMO Backyard Chicken Feed – Layer Formula, 25lbs
This 25-pound bag of crumble is the single most cost-efficient way to deliver 16% protein and balanced nutrition to a flock of laying hens. The crumble form is easier to digest than pellets for older hens, and the non-GMO, antibiotic-free, and gluten-free formulation means you are not passing any synthetic junk into your egg supply. Owners consistently report that hens switch to this feed and resume laying within days after a winter slump.
The protein level hits the 16% minimum that layers need, and the crumble texture reduces selective feeding — hens cannot easily pick out the corn and leave the protein behind. At 25 pounds, a small flock of 6–8 birds will get about three weeks of full feeding, making this a strong option for anyone who wants to buy in bulk without storing multiple small bags.
Some hens initially pick around the corn pieces, but most adjust within a few days once they realize there is no hidden stash of straight corn coming. If you have extremely picky layers, you can mix the crumble with a small amount of cracked corn to ease the transition.
What works
- 16% protein supports steady egg production through molting
- Large 25-lb bag offers the lowest per-pound cost in this lineup
- Non-GMO and antibiotic-free ingredients for cleaner eggs
What doesn’t
- Some hens may take a few days to accept the crumble texture
- No added oyster shell — separate calcium supplement recommended
2. Wholesome Harvest Non-GMO Whole Grain Layer Blend 16%, 10lb
Wholesome Harvest packs three key features into one bag: 16% crude protein from a whole grain mash, oyster shell already blended in for calcium, and flaxseed oil for omega-3 enrichment. This means you do not need to buy a separate calcium supplement or worry about your hens missing their mineral target. The mash form includes cracked corn, soybeans, wheat, and barley, which gives your flock a varied texture that keeps foraging interesting.
Owners with bantam breeds report that a single 10-pound bag lasts noticeably longer than standard scratch because the high protein density keeps hens satisfied longer. The herbs and essential oils in the blend also create a pleasant smell compared to typical feed, and hens seem to respond to the aroma with increased feeding activity.
The 10-pound bag size is the main limitation — if you have more than 10 hens, you will be reordering every week or so. The mash texture can also blow away in windy conditions if you are feeding outdoors, so a covered feeder is recommended.
What works
- Oyster shell included — no separate calcium supplement needed
- Flaxseed oil boosts omega-3 levels in eggs
- Herb and essential oil blend improves palatability
What doesn’t
- 10-lb bag is small for flocks over 10 birds
- Mash texture can blow away in open feeders
3. Purina Layena+ Omega 3 Formula, 10lb
Purina Layena+ is formulated specifically to produce 250 milligrams of omega-3 per large egg, which is a measurable nutritional benefit for anyone selling eggs or eating them daily. The pellet form reduces waste because hens cannot pick out individual grains, and the high-protein vegetarian diet supports consistent eggshell thickness. Owners frequently mention that eggs have noticeably darker yolks and stronger shells after switching from generic layer feed.
The pellet size works well in standard gravity feeders and does not break down into powder as easily as crumbles. The non-GMO claim and the 10-pound bag size make this an easy entry point for new flock owners who want a reliable, proven brand without overthinking the ingredient list.
Availability can be inconsistent — several reviewers note that the product goes out of stock frequently on Amazon. If you rely on auto-ship, keep a backup bag on hand to avoid gaps in feeding. Also, this is a complete feed, not a scratch treat, so it should replace your layer ration rather than supplement it.
What works
- Guaranteed 250mg omega-3 per large egg
- Pellet form minimizes selective feeding and waste
- Proven brand with decades of poultry nutrition research
What doesn’t
- Frequently out of stock — unreliable for auto-ship
- Not a scratch treat; replaces complete layer ration
4. Manna Pro Chicken Scratch Feed, Heritage USA Purple Corn Blend, 10 lb
The signature feature of Manna Pro’s Heritage blend is the inclusion of USA-grown purple corn, which gives the scratch a vibrant color that hens find visually stimulating. The cracked corn texture makes it a true scratch grain — ideal for tossing onto the ground to encourage natural foraging behavior. Owners report that their chickens actually fight over this mix, suggesting the variety of cracked grains keeps interest high compared to plain yellow corn.
As a treat, this scratch is best used as a supplement to a complete layer feed rather than a standalone ration. The 10-pound bag lasts a long time when used as an occasional scatter, and the resealable packaging helps maintain freshness between feedings. Several reviews note that ducks and wild birds also love this blend, so it works well for mixed backyard flocks.
A small number of buyers have reported finding weevils in the bag, which is a risk with any grain-based product. Storing the bag in an airtight container immediately after opening is a smart way to prevent pantry pest issues.
What works
- Purple corn adds visual variety hens find stimulating
- Encourages natural foraging when scattered on ground
- Long-lasting 10-lb bag for treat use
What doesn’t
- Not a complete feed — must be paired with layer ration
- Occasional weevils reported; needs airtight storage
5. GRUBSFARM Premium Chicken Treats 5LB – Black Soldier Fly Larvae
GRUBSFARM black soldier fly larvae deliver an astonishing 85 times more calcium than dehydrated mealworms, making this the single most calcium-dense supplement you can offer a laying hen. The dried larvae are grain-free and pack a high crude protein content that supports feather regrowth during molting and strengthens eggshells without needing oyster shell. The resealable zip-top bag inside a sturdy box keeps the grubs fresh and easy to portion out daily.
Hens go berserk for these — owners consistently report that their flocks come running at the sound of the bag. This makes black soldier fly larvae an ideal training treat for getting hens to return to the coop or for encouraging shy birds to approach. The sustainable production process also recycles food waste, with every pound of larvae diverting 10 pounds of waste from landfills.
Some chickens may prefer mealworms over black soldier fly larvae initially, and you might notice a slight drop in enthusiasm after the first week as the novelty wears off. Rotating between mealworms and larvae can keep excitement high while still delivering the calcium benefits.
What works
- 85x more calcium than mealworms for stronger eggshells
- Grain-free protein source ideal for molting hens
- Resealable packaging keeps product fresh
What doesn’t
- Some hens may prefer mealworms over larvae
- Small 5-lb bag goes fast with larger flocks
Hardware & Specs Guide
Protein: Crumble vs Pellet vs Mash
Crumble is finely ground and easy for all ages to eat but can create dust. Pellets reduce waste and selective feeding. Mash is closest to whole grains but blows away in wind. For laying hens, crumble and pellet forms deliver more consistent protein intake because the ingredients cannot be separated. Mash works best in covered feeders or when scattered in a protected run.
Calcium Fortification Methods
Some feeds incorporate oyster shell or limestone directly into the grain blend, while others require a separate free-choice calcium source. In-feed calcium ensures every bird gets some, but free-choice allows hens to self-regulate based on their laying cycle. Black soldier fly larvae are unique because they deliver calcium in a protein matrix that the hen digests easily without needing an additional supplement.
