This 25-pound bag of organic whole grain mash hits the 17% protein sweet spot for standard-breed pullets and growing ducks while eliminating corn and soy — two common fillers that can trigger digestive sensitivities in young birds. The formulation is certified organic and Non-GMO Project verified, giving you a clean ingredient profile that supports steady feather development without artificial additives.

The whole grain texture gives you the flexibility to feed it dry or fermented. Fermenting the mash prevents selective eating, which is a real advantage with a mixed flock where dominant birds might pick out the tastiest bits and leave the vitamin-fortified granules behind. The eco-friendly packaging is compostable, an important detail if you’re trying to reduce farm waste.

At 25 pounds, you’ll go through it faster with a larger flock, but the nutritional density per pound is excellent for the price tier. Birds on this feed consistently show bright combs and glossy feathering by week 16, indicating the amino acid profile supports proper molt and muscle deposition.

Milled by the 7th-generation Ernst Grain & Livestock family, this 40-pound granule-based feed delivers 19% crude protein using Non-GMO grains fortified with kelp, omega-3s, probiotics, and a diverse essential oil blend. That higher protein makes it a strong candidate for fast-growing meat crosses or dual-purpose breeds raised in cooler conditions where daily feed intake naturally declines.

The inclusion of diatomaceous earth and herbs like oregano and thyme adds an extra layer of gut health support that can help reduce coccidiosis pressure without resorting to medicated feed. Pastured poultry keepers report firmer droppings and less pasty vent in brooder-to-pasture transitions, which suggests the probiotic strains are surviving the pelleting process.

This is a complete ration with no byproducts, so you don’t need additional supplements during the grower phase. The granule form creates less fines than pelleted feeds, meaning less waste at the bottom of the feeder and more consistent intake per bird.

Mile Four sources 100% of its grains from certified organic, Non-GMO family farms across the USA, then mills them fresh into a corn-free and soy-free whole grain formula at 18% protein. The 23-pound pouch includes a sturdy handle for easy carrying, and the bag itself is compostable — a practical touch for homesteaders who want to close the waste loop.

The 18% protein sits between a standard grower and a high-performance broiler ration, making it a versatile choice for mixed flocks containing both standard pullets and a few meat birds. Owners consistently report deep golden yolks once birds enter lay, which signals that the omega-3 and vitamin E profile carries over into egg quality even though this is a grower formula.

Because it’s non-medicated, you’ll need to manage coccidiosis prevention through clean bedding and rotation if you’re raising chicks on wire or in a brooder. The whole grain texture also works well for fermenting, which can help reduce feed intake speed and improve nutrient absorption in aggressive eaters.

This 40-pound granule feed from New Country Organics is built on a simpler formulation with fewer ingredients than most grower rations, yet still delivers 19% protein from certified organic and Non-GMO grains. The corn-free and soy-free profile is designed specifically for pastured poultry systems where birds are already getting some forage-based protein and fiber.

The limited ingredient approach reduces the risk of feed sensitivities, which is particularly helpful when transitioning birds from starter to grower. Keepers using this feed on pasture report that birds maintain good body condition without becoming overly fat, suggesting the energy-to-protein ratio is well-calibrated for active birds that are ranging daily.

The granule form holds up well in treadle feeders and overhead hoppers, creating less dust than mash and less crumbling than pellets. At 40 pounds, the bag size strikes a practical balance between convenience and freshness for flocks of 10 to 25 growing birds.

Kalmbach’s Henhouse Reserve is a 50-pound textured complete feed that combines the appeal of scratch grains with a fully fortified layer ration. The 17% protein content supports continued growth in late-stage pullets while the proprietary LifeGuard blend of prebiotics, probiotics, essential oils, and enzymes promotes digestive health during the transition to egg production.

The Yolk Proud additive is an all-natural ingredient pack that visibly deepens yolk color once the birds begin laying, which is a differentiator if you sell eggs direct-to-consumer and want a consistent dark yolk. The textured form includes whole grains, pellets, and crumbles mixed together, which encourages natural foraging behavior while ensuring balanced intake.

This feed is technically formulated for adult laying hens rather than strict grower-stage birds, so it’s best suited for flocks that are already 16+ weeks and approaching the point of lay. The higher calcium content supports shell quality but should not replace a true grower ration for younger pullets.

Kalmbach’s 50-pound all natural pellet is a plant-based, additive-free layer feed fortified with essential amino acids and elevated calcium levels to produce strong shells. The pellet form reduces sorting behavior and fines, making it a straightforward option for keepers who want a no-fuss feeding routine for their adult flock.

While this is a layer formula rather than a dedicated grower ration, it can serve as a cost-effective maintenance feed for flocks that have already reached full body weight and are in active lay. The absence of animal proteins or fats fits flocks managed under vegetarian-fed labeling programs.

For pullets still in the grower phase, the calcium content here is too high and can interfere with kidney development, so reserve this bag for birds that are already laying regularly. The 50-pound size offers solid value for keepers with established laying flocks looking for a clean, simple ingredient deck.

Purina’s Layena Crumbles is a 50-pound high-protein layer feed that includes marigold extract to naturally enhance yolk color, along with calcium, manganese, and trace minerals for shell integrity. The crumble form is easier for smaller-beaked breeds to consume than large pellets, reducing the time birds spend at the feeder.

This is a veterinary diet formulation intended for adult laying hens, not for grower-stage pullets. The protein level is higher than standard layer rations, which can help maintain body condition in high-production hens but may promote excessive weight gain in younger birds that are still developing their frame.

For keepers looking to transition a flock from grower to layer feed, the crumble texture provides a familiar particle size that birds accept quickly. The added marigold extract gives yolks a market-fresh orange hue, which is a visible benefit if you’re selling eggs at a farm stand.
