The 10 Best Vitamins For Chickens

Hens are one of the easiest animals to care for, and their diet readily meets the majority of their nutritional demands, especially free-range chickens.

While carbs, lipids, protein, and minerals are all important for your flock's health and welfare, vitamins enable your chicken's body correctly absorb all of the other elements in their food, laying the groundwork for a well-functioning immune system and optimum growth and development.

Most vitamins cannot be manufactured by chickens in significant quantities, thus they must be obtained through their feed. Vitamins are especially crucial for laying hens, who require an extra boost to be healthy while producing eggs practically every day.

Vitamins are particularly important for hens who are not allowed to roam freely since they cannot obtain these micronutrients via foraging. Vitamin A and D insufficiency can both result in fewer eggs and eggs with fragile, weak shells.

In this post, BestForPets (bestforpets.org) will look at the best vitamins for chickens on the market so that you may limit down your choices and choose the ideal one for your needs.

Buyers Guide

Vitamins and minerals are vital for the health and well-being of chickens, and while free-range chickens fed a good diet will normally obtain what they need without supplementation, supplementing throughout the winter months and for laying hens will undoubtedly assist.

Multivitamins are also beneficial to developing chicks, allowing them to get off to a healthy start.

Vitamins are excellent supplements for times of stress, such as environmental changes, cold spells, breeding, and for sick or injured birds. Whether you have a backyard flock in a coop or free-range hens, vitamin supplementation in their food will undoubtedly help them.

Important factors to consider while purchasing vitamins for your flock

Not all vitamin supplements are created equal, and many contain other components such as probiotics and extra minerals, making it difficult to find the correct supplement.

In general, these additives are beneficial to your flock and will provide them with additional health benefits.

Powder vs. pellets

Pellets are ideal since you can just put the needed amount into your chicken’s feed, making it a quick and easy way to supplement your flock.

However, if the pellets are unpalatable, your birds will simply ignore them and pick out the grains. If this happens, you may wish to turn the pellets into a mush that is more appealing to them.

Powdered vitamin supplements are ideal since they can be blended into your bird’s water or coated onto their meal, ensuring that your hens receive the necessary nourishment.

Of course, if your supplement gets wet or expires, it will clump and become ineffective. Some powdered vitamins do not dissolve well in water, thus they must be mixed into the dry diet.

Chickens require certain vitamins.

Except for vitamin C, chickens require all vitamins in their diet. Your flock requires the following vitamins:

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

The majority of these vitamins should be obtained through your flock’s diet, but it’s a good idea to supplement during tough winters, when laying, or if you create your own feed.

Vitamin and mineral deficiencies in hens

Many, if not all, of the health issues encountered in home flocks may be prevented by providing your chicken with a nutritious, balanced diet rich in critical vitamins and minerals.

Even if they are low in only one vitamin, it can have a major impact on their capacity to absorb other nutrients, resulting in a cascade effect.

Unfortunately, a vitamin shortage can create health problems in your hens long before they exhibit any visible signs, but here are a few to look out for:

  • Poor feathering in general
  • Poor or insufficient laying
  • Slow expansion
  • Deformities
  • Lethargy
  • Appetite loss
  • Weight reduction
  • Divider for chickens


Our preferred vitamin supplement for hens is Rooster Booster's pelleted mineral and vitamin supplement . It is developed for all phases of growth and all classes of poultry, and it contains critical vitamins and minerals as well as probiotics to maintain a healthy immune system and digestion.

DURVET's vitamin and electrolyte blend  is also a favorite of ours. This water-soluble vitamin and electrolyte premix is great for laying and developing chickens, and it contains vitamins A, D, and E, as well as minerals like potassium and calcium.

With so many vitamin supplements on the market today, it can be difficult to choose the best vitamins for chickens. Hopefully, BestForPets‘ (bestforpets.org) in-depth evaluations have helped you narrow down your selections and select the finest supplement for your needs.
