Why I Recommend Calcium Supplement For Chickens

As a chicken owner, I have learned the importance of providing my feathered friends with a well-balanced diet. One crucial element that should not be overlooked is calcium. Just like humans, chickens also require calcium for strong bones, eggshell production, and overall health.

Chickens that are lacking in calcium can develop weak and brittle bones, making them more susceptible to fractures and injuries. This can lead to serious health issues and even death in severe cases. Additionally, without enough calcium in their diet, hens may lay eggs with thin or soft shells, making them prone to breakage.

In order to meet their daily calcium requirements, chickens need access to a good source of calcium. While some may argue that free-range chickens can get enough calcium from foraging, it’s important to keep in mind that not all soils are rich in this mineral. Moreover, during winter months or when there is limited access to greenery, providing a supplement becomes even more vital.

There are various types of calcium supplements available for chickens such as crushed eggshells, oyster shells, limestone grits, and commercially available supplements. Whichever option you choose, make sure it is easily accessible to your chickens at

My Buying Guide on ‘Calcium Supplement For Chickens’

As a chicken owner, I understand the importance of providing my feathered friends with a well-balanced diet to keep them healthy and happy. One essential nutrient that chickens need is calcium, which is crucial for egg production, strong bones, and overall health. However, sometimes their regular feed may not provide enough calcium, especially for young or older chickens. That’s where calcium supplements come in. In this buying guide, I’ll share my experience and knowledge on purchasing the right calcium supplement for chickens.

Why do chickens need calcium supplements?

Before diving into the buying guide, let’s first understand why chickens need calcium supplements. Calcium is essential for egg production as it helps in forming strong and sturdy eggshells. If a hen doesn’t have enough calcium in her diet, she might lay eggs with weak shells or even stop laying altogether. Additionally, calcium is crucial for maintaining bone health and preventing conditions like soft-shelled eggs or osteoporosis in older hens.

Types of Calcium Supplements

There are various types of calcium supplements available for chickens, such as oyster shells, limestone grits, crushed eggshells, and commercial poultry calcium supplements. Each type has its benefits and drawbacks; therefore, it’s essential to consider your flock’s specific needs before deciding on a supplement.

Oyster Shells

Oyster shells are a popular choice among chicken owners as they are a natural source of calcium and contain other minerals like phosphorus and magnesium. They can be offered separately from the regular feed or mixed into their feed. However, oyster shells can be sharp and may cause injury to your flock if not crushed properly.

Limestone Grits

Limestone grits are small stones that provide a source of dietary calcium for chickens. They also help in grinding up food in the gizzard to aid digestion. However, they should be used cautiously as too much grit can cause impaction in the digestive system.

Crushed Eggshells

If you have backyard chickens that lay eggs regularly, you can save their eggshells and crush them into small pieces to feed back to them as a source of calcium. This option is cost-effective but may not be sufficient for large flocks.

Commercial Poultry Calcium Supplements

If you prefer convenience and want to ensure your flock gets an adequate amount of calcium daily without any hassle, then commercial poultry calcium supplements are your best bet. They come in different forms such as powder or pellets and are specifically formulated for poultry with added vitamins and minerals.

Considerations when buying Calcium Supplements

When purchasing a calcium supplement for your chickens, there are a few factors you should consider:

  • Type: As mentioned earlier, consider which type of supplement will best suit your flock’s needs.
  • Poultry-specific: Make sure the supplement is specifically formulated for poultry as other types may contain ingredients that could be harmful to your birds.
  • Inclusion rate: Check the recommended inclusion rate on the packaging to ensure you’re providing your flock with the correct amount of supplementation.
  • Certifications: Look out for certifications from reputable organizations such as USDA Organic or Non-GMO Project Verified to ensure the product is safe for consumption.
  • User reviews: Lastly, read reviews from other chicken owners who have used the product to get an idea of its effectiveness.

Budget-friendly options

If you’re on a tight budget but still want to provide your flock with enough calcium supplementation without compromising quality, here are some tips:

  • Purchase bulk quantities instead of smaller packages as they tend to be more cost-effective in the long run.
  • You can also mix different types of supplements together (e.g., oyster shells with crushed eggshells) to create a balanced mix at a lower cost.
  • If you have access to natural sources such as seashells or limestone rocks that can be crushed into grits or powdered form at home – this will save money while still providing necessary nutrients.

In conclusion

Selecting the right calcium supplement for your chickens may seem overwhelming at first with so many options available. But by considering factors like type, inclusion rate, certifications, and user reviews while keeping budget-friendly options in mind – you’ll surely make an informed decision that will benefit your flock’s health in the long run!
