If you’re a chicken keeper, you’ve probably noticed your feathered friends pecking at eggshells after they’ve finished laying. But have you ever wondered why they do this? It’s not just a quirky habit – chickens eating eggshells is actually a natural behavior that can be linked to their dietary needs. Calcium is an essential nutrient for chicken health, and eggs shells are a convenient source of this vital mineral. However, eating eggshells can also pose some risks, especially if they’re contaminated with bacteria or other substances. In this article, we’ll delve into the world of chickens and calcium, exploring why they eat eggshells and what you need to know to keep them safe and healthy.
The Importance of Calcium in Chicken Diets
Calcium is a crucial nutrient for chickens, and eggshells just happen to be an excellent source that they can easily incorporate into their diets. Let’s explore why it matters so much.
Role of Calcium in Eggshell Formation
Calcium plays a vital role in eggshell production, and it’s essential for chickens to have a balanced diet that meets their calcium needs. When hens are laying eggs, they need a steady supply of calcium to create the hard, protective shell around their developing chicks. If a hen doesn’t get enough calcium, her body will use whatever is available, including bones, teeth, and even her own tissues. This can lead to weakened eggshells that may crack or break easily.
To ensure healthy eggshell formation, chickens need access to a diet rich in calcium, as well as other essential nutrients like phosphorus, vitamin D3, and energy sources. A balanced feed should provide around 2-4% calcium content to support strong eggshell production. You can also supplement their diet with crushed eggshells or oyster shells, which are excellent sources of slow-releasing calcium. By providing your flock with a well-rounded diet, you’ll not only promote healthy eggshell formation but also overall chicken health and vitality. This is where chickens getting into the habit of eating eggshells can actually help them get more calcium in their diets.
Sources of Calcium in Chicken Feed
When it comes to commercial chicken feed, there are several sources of calcium that can help meet a chicken’s daily requirements. One common source is crushed oyster shells, which are rich in calcium carbonate and often added to layer feed to promote strong eggshell production. Limestone is another popular option, providing a steady supply of calcium throughout the flock.
Dolomitic limestone, on the other hand, offers an even more comprehensive blend of minerals. In addition to calcium, it contains magnesium and other essential nutrients that support overall health and well-being. As you consider your own flock’s diet, keep in mind that a balanced feed is just as important as access to eggshells themselves.
Many commercial feeds already contain these sources of calcium, so be sure to check the ingredient list before making any changes. If you’re looking for ways to supplement your chickens’ diets further, consider adding crushed oyster shells or dolomitic limestone to their feeding troughs a few times a week. This will not only support strong eggshell production but also provide a welcome treat for your feathered friends.
Why Chickens Might Eat Eggshells
You might be wondering, but is it normal for chickens to eat their own eggshells? Let’s explore some reasons behind this behavior.
Protein Deficiency or Malnutrition
When chickens are not getting enough protein in their diet, they may resort to eating eggshells as a way to supplement their nutrient intake. This is often due to malnutrition or a lack of essential nutrients such as calcium, phosphorus, and amino acids. Chickens need about 1-2% calcium in their diet to maintain strong bones and eggshell production.
If your chickens are not getting enough protein, they may eat eggshells to compensate for the deficiency. In fact, studies have shown that when hens are fed a low-protein diet, they will consume more eggshells as a way to get the nutrients they need. To avoid this problem, make sure to provide your flock with a balanced and nutritious feed that contains at least 16-18% protein.
You can also supplement their diet with calcium-rich foods such as oyster shells or crushed eggshells, but make sure to mix them well into their feed to prevent overconsumption.
Boredom or Lack of Mental Stimulation
Chickens might eat eggshells due to a lack of mental stimulation, and this behavior is often linked to boredom. A chicken’s cognitive abilities are not just limited to foraging and scratching, but also extend to problem-solving and learning new things. When their environment is static and predictable, chickens can become easily bored, leading them to engage in abnormal behaviors like eating eggshells.
Stress is another factor that can contribute to this behavior. Chickens experience stress when they’re not provided with enough space or mental stimulation. A lack of variety in their diet, for example, can lead to stress, which might cause them to eat eggshells as a coping mechanism. To address this issue, it’s essential to enrich your chicken’s environment by introducing new toys, perches, and activities.
Providing foraging opportunities is another way to keep your chickens engaged and stimulated. You can create a foraging station using cardboard boxes or wooden dowels filled with treats like sunflower seeds or mealworms. This will challenge your chicken’s problem-solving skills and keep them entertained for hours.
Benefits of Chickens Eating Eggshells
You might be wondering if it’s a good idea to let your chickens snack on eggshells, and the answer is yes! Here are some amazing benefits for their health and well-being.
Calcium Supplement for Stronger Bones
When you’re feeding your chickens eggshells, you may wonder what benefits they could possibly get from eating something they’ve already laid. One of the most significant advantages is that it provides an additional source of calcium for stronger bones and overall health.
Eggshells are rich in calcium carbonate, a form of calcium that’s easily absorbed by birds. Chickens need calcium to maintain strong bone structure, as well as for healthy egg production. Without sufficient calcium, they may develop conditions like osteoporosis or even stop laying eggs altogether. By feeding them their own eggshells, you’re essentially giving them a free and natural source of this essential nutrient.
To incorporate eggshells into your chickens’ diet, simply crush them into small pieces and mix with their regular feed. You can also sprinkle crushed eggshells around their coop or run to provide an easy snack. Just be sure to wash the eggshells thoroughly before crushing them to remove any bacteria that may be present on the surface.
Reduced Health Risks Associated with Malnutrition
When chickens eat eggshells, they’re not only reducing waste but also potentially lowering their risk of developing health issues related to malnutrition. Malnutrition can be a significant problem for backyard chickens, especially if their diet is lacking essential nutrients.
One key nutrient often found deficient in commercial layer feed is calcium. Chickens require adequate calcium intake to maintain strong bones and prevent conditions like osteoporosis and eggshell mending disorders. When they eat eggshells, which are rich in calcium carbonate, they’re addressing this nutritional gap. In fact, research suggests that supplementing chicken diets with crushed eggshells can improve bone density and reduce the incidence of fractures.
By incorporating eggshells into their diet, you can help your flock maintain optimal health while reducing waste and the environmental impact of discarded shells. So next time you collect eggs from your coop, consider crushing a few eggshells to add to their feed – it’s an easy way to provide them with essential nutrients!
The Potential Dangers of Chickens Eating Eggshells
If your chickens are devouring their eggshells, you’re probably wondering if it’s safe for them to be eating these calcium-rich treats. We’ll explore some potential risks associated with this behavior in more detail below.
Risk of Salmonella and Bacterial Contamination
Eating eggshell fragments can be detrimental to your chickens’ health, and one of the most significant risks is the potential for salmonella and bacterial contamination. When chickens consume crushed eggshells, they may ingest tiny pieces that contain bacteria like Salmonella Enteritidis or Salmonella Heidelberg. These pathogens can cause severe illness in birds, leading to symptoms such as diarrhea, lethargy, and even death.
The risk of contamination is higher when hens are stressed or malnourished, making them more susceptible to illnesses caused by bacterial consumption. Even if your flock appears healthy, there’s always a chance that some birds may be carriers of the bacteria without showing any signs. To minimize this risk, it’s essential to ensure your chickens have access to clean water and balanced nutrition.
If you notice your hens consistently eating eggshells, consider providing them with crushed oyster shells or cuttlebone as an alternative source of calcium. This will satisfy their nutritional needs while eliminating the risk of bacterial contamination from consuming eggshell fragments. Regular health checks and maintaining a clean coop can also help prevent the spread of diseases in your flock.
Internal Damage or Obstruction
If your chickens are consuming large quantities of eggshell fragments, it can lead to internal damage or obstruction. The sharp edges of the shells can cause punctures in their digestive tract, potentially leading to peritonitis, an inflammation of the lining surrounding the abdominal organs. In severe cases, this can be life-threatening.
Eggshells can also become lodged in your chicken’s intestines, causing a blockage that prevents food from passing through normally. This can lead to vomiting, diarrhea, and weight loss. You may notice changes in your chicken’s behavior, such as lethargy or loss of appetite, which are signs that something is amiss.
To minimize the risk of internal damage or obstruction, it’s essential to provide a balanced diet for your chickens. Make sure they have access to calcium-rich foods like oyster shells or crushed eggshells in moderation. Avoid leaving large pieces of eggshell on the floor, and consider adding grit or small rocks to help them grind up any undigested food.
Regularly monitoring your chicken’s health and behavior is crucial in identifying potential issues early on. Keep an eye out for signs of internal damage or obstruction, and seek veterinary attention if you notice any unusual symptoms.
How to Prevent Chickens from Eating Eggshells
If you’re tired of finding eggshell-strewn coops, don’t worry – we’ve got some practical tips on how to keep your chickens from eating their own eggs.
Provide Adequate Calcium-Rich Feed
To prevent chickens from eating eggshells, it’s essential to provide them with an adequate supply of calcium-rich feed. Chickens need a diet rich in calcium to support strong bone growth and development, particularly during the laying stage. A deficiency in calcium can lead them to seek out alternative sources, such as eggshells.
Feed manufacturers often fortify their products with added calcium supplements to meet these needs. However, you may not always know what’s included in your commercial feed or whether it meets your flock’s requirements. As a result, it’s crucial to monitor your chickens’ feed quality and adjust accordingly.
Ensure that your chickens receive 1-2% of their daily diet as calcium through their feed alone. This can be achieved by offering dark leafy greens like kale, spinach, and collard greens in moderation. You can also provide oyster shells or crushed eggshells on the side to supplement their diet. However, always follow proper food safety guidelines when offering external supplements.
By providing your chickens with a balanced, calcium-rich feed, you’ll reduce the likelihood of them seeking out eggshells as a source of calcium.
Offer a Variety of Mental Stimulation and Activities
Boredom and stress can lead to chickens seeking out eggshells as a source of calcium and mental stimulation. To redirect their attention away from eggs, provide a variety of activities that cater to their natural behaviors. Chickens are intelligent birds that require mental stimulation to prevent boredom.
Create a foraging area with hidden treats or toys filled with seeds, grains, or even sunflower seeds. This activity will challenge your chickens’ problem-solving skills and encourage them to search for food. You can also hang chicken-safe plants like lavender or rosemary near their coop to provide visual interest and a sense of exploration.
Other activities that can keep your chickens engaged include offering puzzles or treat-dispensing toys, setting up a “digging station” with sand or soil, or creating a climbing structure for exercise. Rotate these activities regularly to prevent boredom and keep your chickens stimulated and active. By providing variety and mental stimulation, you’ll reduce the likelihood of egg consumption.
