8 Best Vitamins for Chickens in 2021 – Reviews & Top Picks

Coop Kelp Organic Chicken and Duck Feed Supplement in a scooper

Chickens are one of the easiest animals to care for, and most of their nutritional needs are easily met through their diet, especially free-range chickens. While nutrients like carbohydrates, fats, protein, and minerals are all essential to the health and wellness of your flock, vitamins help your chicken’s body properly absorb all the other nutrients in their diet, providing the basis for a well-functioning immune system and optimum growth and development. Most vitamins cannot be synthesized by chickens in sufficient amounts, so they need to come from their diet.

Vitamins are especially important for laying hens, as they need the extra boost to help them maintain optimum health while producing eggs almost daily. Vitamins are also vital for chickens that are not left to free-range, as they cannot get these micro-nutrients from foraging. Both vitamin A and vitamin D deficiency can result in fewer eggs, as well as eggs with brittle, weak shells.

In this article, we look at the best vitamins available on the market, so you can narrow down the options and find the best one for your needs.

  • The 8 Best Vitamins for Chickens — Reviews 2021

    1. Rooster Booster Poultry Booster Pellet Vitamin Supplement — Our Top Pick Overall

    Rooster Booster Poultry Booster Pellet Vitamin Supplement

    This pelleted mineral and vitamin supplement from Rooster Booster is formulated for all stages of growth and all classes of poultry. The supplement comes loaded with essential vitamins, including vitamin D3 and vitamin B12; minerals, like calcium and magnesium; and amino acids, which are essential for laying hens. The formula is also loaded with probiotics to help support a healthy immune system and healthy digestion. Simply mix one of the included 1/3-ounce scoop into a pound of feed to give your chickens the vitamin and mineral boost that they need.

    The only drawback with these pelleted vitamins is that some chickens may pick out the other food and leave the pellets behind, so you may need to make them into a powder or mash to get the full benefits.

    Pros
    • Suitable for all growth stages
    • Added minerals
    • Includes vitamins D3 and B12
    • Contains added probiotics
    Cons
    • Some chickens may not eat the pellets

    2. DURVET 136028 Vitamins & Electrolytes

    DURVET 136028 Vitamins & Electrolytes

    This three-pack of vitamins and electrolytes from DURVET is a premix of water-soluble vitamins and electrolytes, ideal for laying and growing hens. The mix contains vitamins A, D, and E and added minerals like potassium and calcium. A little goes a long way with this mix — around 1/2 a teaspoon per gallon of water is plenty for chickens. Because it’s water soluble, they won’t be able to leave any behind, so you have the peace of mind that they are getting a balanced mix.

    The premixed packets, unfortunately, do not have any expiration dates listed, and some customers received packages with clumped powder. This small issue keeps this supplement from the top spot on this list.

    • Convenient three-pack
    • Added electrolytes
    • Added minerals
    • Water-soluble
    • Inexpensive
    Cons
    • No expiration date

    Buyers Guide

    Vitamins and minerals are essential to the health and well-being of chickens, and although free-range chickens fed on a healthy diet will usually get all that they need without supplementation, it can certainly help to supplement during winter months and for laying hens. Multivitamins are also great for growing chicks, helping them get a good, healthy start.

    Vitamins are great additions for times of stress, such as changes in the environment, during cold spells and breeding, and for birds that are poorly or ill. Whether you have a backyard flock in a coop or free-range chickens, they will definitely benefit from vitamin supplementation in their diet.

    Important considerations when purchasing vitamins for your flock

    Not all vitamin supplements are made equal, and most contain other ingredients, like probiotics and added minerals, which can make it confusing to choose the right supplement. In general, these additions are great for your flock regardless and will give them an extra health boost.

    Pellets vs. powder

    Pellets are great because you can simply mix the required amount into your chicken’s feed, and it’s an easy way to give your flock their required supplement. However, if the pellets are not palatable, you’ll find that your birds will simply leave them alone and pick out the grains. If this does occur, you may want to make the pellets into a mash that is more palatable to them.

    Powdered vitamin supplements are great because they can be mixed into your bird’s water or coated onto their food, so it’s guaranteed that your chickens get the required nutrition. Of course, if your supplement gets wet or expires, it will clump, rendering it useless. Some powdered supplements don’t mix well in water, so they’ll need to be added to the dry feed.

    Essential vitamins for chickens

    In general, chickens require all vitamins in their diet apart from vitamin C. The most important vitamins needed by your flock are:

    • Vitamin A (aids in egg production and growth)
    • Vitamin D (strengthens eggshells and increases egg production)
    • Vitamin E (for general growth and reproduction)
    • Vitamin K (healthy blood and muscle health)
    • Vitamin B1 (carbohydrate metabolism)
    • Vitamin B2 (important for growth)

    Your flock should get most of these vitamins from their feed, but it’s a great idea to supplement during harsh winters, while laying, or if you make your own feed.

    Signs of vitamin and mineral deficiency in chickens

    Many, if not all, of the health problems found in backyard flocks can be avoided by giving your chicken a healthy, balanced diet complete with all the essential vitamins and minerals. Even if they are deficient in just one nutrient, this can have a significant effect on their ability to absorb other nutrients and cause a cascading effect. Unfortunately, a deficiency in vitamins can cause health issues long before your chickens show any noticeable symptoms, but here are a few to look out for:

    • General poor feathering
    • Poor or reduced laying
    • Slow growth
    • Deformities
    • Lethargy
    • Lack of appetite
    • Weight loss
