Medicated vs. Non-Medicated: Key Differences

The fundamental difference between these feeds is a single, specific additive. Medicated chick starter contains a drug called amprolium, a coccidiostat designed to prevent an outbreak of coccidiosis. Coccidiosis is a common and often fatal intestinal parasite that thrives in the warm, damp conditions of a brooder.

Amprolium works by mimicking thiamine (Vitamin B1), which the coccidia parasite needs to multiply. The parasite absorbs the amprolium instead of the thiamine, effectively starving it and preventing it from overwhelming a chick’s young system. It’s a preventative measure, not a cure for an active, severe infection.

Non-medicated feed is simply a complete starter ration without the amprolium. It provides all the necessary protein, vitamins, and minerals for healthy growth but offers no protection against coccidia. Choosing this path places the responsibility for coccidiosis prevention squarely on your brooder management and hygiene practices.

Here’s the breakdown:

• Medicated Feed: Contains amprolium to prevent coccidiosis. Ideal for beginners, crowded brooders, or when you can’t guarantee perfectly dry bedding.
• Non-Medicated Feed: Contains no coccidiostat. Best for chicks vaccinated for coccidiosis or for experienced keepers with meticulous hygiene and low-density brooders.

Purina Start & Grow Medicated for Coccidiosis

Purina Start & Grow is one of the most widely available and trusted medicated feeds on the market. Think of it as the standard, reliable choice for getting a new flock off the ground. Its formulation is consistent, providing the 18% protein chicks need for healthy development alongside the amprolium for coccidiosis prevention.

This feed is a workhorse. It’s designed for the typical hobby farm scenario where chicks arrive stressed from shipping and are introduced into a brooder that, despite your best efforts, can become damp. The inclusion of amprolium provides a crucial safety net during the most vulnerable period of a chick’s life, from day one to around 8-10 weeks.

Choosing Purina Medicated is a pragmatic decision, especially for your first year. It reduces one major variable—a sudden coccidiosis outbreak—allowing you to focus on mastering temperature, hydration, and clean bedding. It’s the feed you choose when you want to minimize risk and ensure your chicks have a strong, healthy start without any guesswork.

Nutrena NatureWise Non-Medicated Starter Feed

Nutrena’s NatureWise line represents a mainstream move toward a more "natural" approach without medication. This feed is an excellent choice if you’ve specifically purchased chicks that were vaccinated for coccidiosis by the hatchery. Using medicated feed on vaccinated chicks will cancel out the vaccine’s effectiveness.

This non-medicated crumble is formulated with gut health in mind, often containing prebiotics and probiotics to support a chick’s developing digestive system. The idea is to build a robust internal environment that can naturally resist pathogens. It’s a proactive, health-forward approach rather than a purely preventative one.

Opting for NatureWise Non-Medicated means you are confident in your husbandry. Your brooder needs to be kept impeccably clean and dry, with plenty of space for the chicks to avoid trampling feces. It’s a great feed, but it requires a higher level of management than its medicated counterparts.

Manna Pro Medicated Starter for Brooder Health

Manna Pro offers another excellent medicated starter, often seen as a direct competitor to Purina. While also built around amprolium for coccidiosis prevention, its formulation often emphasizes a slightly different blend of vitamins and minerals to support overall health and immunity.

This feed is a fantastic option for anyone wanting the security of a medicated ration but perhaps looking for a specific nutritional profile. It provides the same 18% protein and coccidiosis prevention you need, but with Manna Pro’s particular focus on a complete nutritional package. It’s a solid, dependable choice for ensuring your chicks thrive.

Think of Manna Pro as a comprehensive insurance policy. You get the critical coccidiosis prevention while also providing a feed fortified to support bone development, feather growth, and immune function. It’s a popular choice at farm supply stores and has a loyal following for a reason.

Scratch and Peck Feeds Organic Non-Medicated

For the keeper committed to an organic, non-GMO, and soy-free flock from day one, Scratch and Peck is the gold standard. This feed is a whole-grain, non-medicated product that meets the highest standards of organic certification. It’s the least processed option you’ll find in a bag.

Choosing this feed is a philosophical and a practical decision. It aligns with a specific approach to agriculture, but it also demands the highest level of brooder management. With no coccidiostat and a focus on whole grains, you must be vigilant about keeping the brooder bone-dry and providing chick-sized grit to aid digestion.

The tradeoff is cost and labor. Scratch and Peck is a premium feed with a corresponding price tag. It also requires you to be an expert at managing your brooder environment, as there is absolutely no medicinal safety net. This is the choice for a dedicated keeper who prioritizes organic inputs above all else.

Dumor Medicated Chick Starter from Tractor Supply

Dumor is Tractor Supply’s house brand, and it offers a practical, budget-friendly medicated chick starter. This feed is designed to meet all the essential requirements for starting chicks without the premium price of national brands. It contains the necessary protein levels and amprolium to get the job done.

This is the feed for the pragmatic flock owner. If you’re raising a larger batch of chicks, whether for meat or eggs, feed costs add up quickly. Dumor provides the essential coccidiosis prevention and nutrition needed to raise healthy birds without breaking the bank.

Don’t mistake its lower price for lower quality. It’s a perfectly balanced ration that provides the safety net of medication. For many hobby farmers, it’s the smartest financial and practical choice, delivering excellent results and healthy, thriving chicks.

Kalmbach Henhouse Reserve Non-Medicated Option

Kalmbach’s Henhouse Reserve is a premium non-medicated starter that bridges the gap between basic feeds and high-end organic options. It’s for the keeper who has decided against medication but still wants to invest in superior nutrition for their flock.

This feed stands out by focusing heavily on digestive health. It is often formulated with a proprietary blend of prebiotics, probiotics, and enzymes designed to build a strong gut microbiome from the start. The goal is to create chicks that are naturally more resilient to environmental stressors and pathogens.

Choosing Henhouse Reserve is an intentional investment in your flock’s long-term health. It’s ideal for vaccinated chicks or for keepers with pristine brooder setups who believe that building a strong gut is a better preventative measure than medication. It’s a sophisticated choice for the discerning chicken keeper.

Matching Starter Feed to Your Brooder Setup

The best chick starter isn’t about the brand on the bag; it’s about the conditions in your brooder. Your decision should be based on a realistic assessment of your specific situation. There is no single right answer, only the right answer for you.

Consider these key factors before you buy:

• Vaccination Status: This is the most important factor. If your chicks were vaccinated for coccidiosis at the hatchery, do not use medicated feed. The amprolium will render the vaccine useless. Always use a non-medicated starter for vaccinated birds.
• Brooder Conditions: Be honest with yourself. Is your brooder in a damp basement or a dry, climate-controlled room? Will the chicks be crowded? The risk of a coccidiosis outbreak is much higher in warm, humid, and crowded conditions, making medicated feed a very wise choice.
• Source and Stress: Chicks shipped through the mail endure significant stress, which weakens their immune systems. Medicated feed provides an important buffer for these vulnerable birds. In contrast, chicks hatched quietly under a broody hen in your backyard are far less stressed and may do perfectly fine on non-medicated feed.

Ultimately, the choice comes down to risk management. Medicated feed is cheap insurance for a first-time owner or anyone with a less-than-perfect brooder environment. Non-medicated feed is an excellent option for vaccinated chicks or for experienced keepers who can control moisture and cleanliness with absolute precision.

Choosing the right starter feed is your first major act of flock stewardship. By matching the feed to your chicks’ vaccination status and your brooder’s reality, you set them up for success. Get this right, and you’re well on your way to raising a healthy, vigorous flock.
