Oyster shells are a great source of calcium for chickens and can help strengthen their eggshells. While oyster shells are beneficial for most chickens, they are not necessary for all. It is recommended that oyster shells are only given to hens that are already laying eggs, as they will require four times as much calcium as non-laying hens. It is also important to note that oyster shells should be baked at 350 degrees Fahrenheit for 10 minutes to kill any bacteria, and then crushed finely so that the hens do not mistake them for their own eggshells. For silkie chickens, which are a breed that takes more time off between laying eggs, the amount of calcium required will vary, and their bodies will prompt them to eat oyster shells as needed.
| Characteristics | Values |
|---|---|
| When to start giving oyster shell to silkie chickens | Only start giving oyster shells to silkies after they have started laying eggs. Silkies take more time off from laying eggs than other breeds, so their bodies will prompt them to eat oyster shells as they need the extra calcium. |
| How to prepare oyster shells | Bake raw oyster shells at 350 degrees Fahrenheit or 121 degrees Celsius for 10 minutes to kill any bacteria. Then, crush them finely so they do not resemble egg shells. Oyster shells can be purchased from feed stores or grocery stores, and are often pre-ground. |
| How much oyster shell to give | Oyster shells should be provided year-round in a separate feed bowl, but the amount of calcium a hen needs is an individual issue. Hens that lay more eggs will need more calcium. |

Oyster shell is a good source of calcium for laying hens
Oyster shell is a great source of calcium for laying hens. It is inexpensive and lasts a long time as it does not spoil or go bad. Oyster shell is also an excellent way to increase the amount of calcium in a hen's diet as it dissolves in the gut. It is not the same as grit, which aids digestion by grinding up food in the crop. Oyster shell is meant only to add calcium to the diet of your laying hens.
Calcium is an essential nutrient for laying hens as it helps them lay well and keeps them healthy. An egg contains 94-97% calcium carbonate, which is a lot of calcium to pull from a hen. If a hen doesn't get enough calcium in her diet, she will steal it from the calcium stored in her bones, which can cause osteoporosis and make it difficult for her to stand. A lack of calcium can also lead to a drop in egg production or failure to start laying, lameness, and behavioural problems such as pecking and increased overall activity.
To avoid these issues, it is recommended to offer a source of calcium like oyster shell, free choice so they can take as much as they want. Oyster shell should be given in a separate bowl and not mixed with their food. Hens will instinctively know to take it when they need it and will lower their intake when they aren't laying as much.
While eggshells can also be fed back to hens as a source of calcium, they don't contain the same fast-release calcium that oyster shells do. Eggshells must be baked first to kill any bacteria and crushed finely so that they don't look like egg shells, otherwise, you are teaching the hens to eat their own eggs.

Hens need calcium to lay eggs with strong shells
Oyster shells are an important source of calcium for laying hens. Hens need calcium to lay eggs with strong shells. The more eggs they lay, the more calcium they need. When a hen doesn't get enough calcium in her diet, her eggshells will be weaker. If your hen's eggs break easily, this may be a sign that you need to supplement their diet with oyster shells.
Oyster shell supplements are typically available at feed stores and are relatively inexpensive. They can be purchased whole or pre-ground. If you collect oyster shells yourself, it is important to bake them at 350 degrees Fahrenheit (176 degrees Celsius) for 10 minutes to kill any bacteria. You can then crush them into a fine powder, being careful not to make them look like eggshells, as this may encourage the hens to eat their own eggs.
It is important to note that oyster shells should not be fed to pullets that haven't started laying eggs yet. Hens that are not laying will get enough calcium from their daily feed. It is only when they start laying that they need four times as much calcium as a non-laying hen. Most hens start to lay at around 20 weeks of age, and this is when you can begin offering oyster shell supplements.
The amount of calcium a hen needs can vary between individuals and breeds. Some breeds, like silkies, take more time off between laying eggs. The hen's body will prompt her to eat oyster shells as needed, so it is a good idea to provide a separate bowl of oyster shells that is freely available to them throughout the year. This way, they can self-regulate their calcium intake and stay healthy.

Oyster shell is also referred to as soluble grit
Oyster shell supplements are important for laying hens to ensure they get enough calcium. Calcium is needed to produce strong eggshells, and a lack of calcium can cause hens to produce weak or irregularly shaped eggs. It can also lead to slow laying, or problems like egg eating. In severe cases, a lack of calcium can cause osteoporosis and trouble standing.
While oyster shell is a source of calcium, it is not the same as grit. Grit is needed to aid digestion by grinding up food in the crop. Oyster shell does not aid digestion and does not stimulate egg laying. It simply provides calcium to the hen.
It is important to provide both oyster shell and grit to your chickens, as they serve distinct functions in their health and wellbeing. Oyster shell should be offered free choice in a separate bowl, so hens can eat as much as their body needs. Grit should also be provided free choice, and chickens will instinctively know how much to eat.

Hens will eat oyster shell when their bodies need calcium
Oyster shell supplements are an important component of a laying hen's diet. They are a great source of calcium, which is essential for egg-laying hens to produce quality eggshells. In fact, an egg contains 94-97 percent calcium carbonate, which is pulled from the hen's body. Oyster shell supplements are a great way to increase the calcium in a hen's diet, as they are inexpensive, long-lasting, and do not spoil.
Hens will eat oyster shells when their bodies need calcium. Oyster shells should be provided separately from food, in a bowl or feeder, and the hen will instinctively know to take it when she needs it. Hens that lay frequently will need more oyster shells than those that lay less often. This is because the more eggs a hen lays, the more calcium she needs. If a hen does not get enough calcium, she will steal it from the calcium stored inside her bones, which can cause osteoporosis and make it difficult for her to stand. Therefore, it is important to provide oyster shells all year round, even if the hen is not laying as many eggs during certain periods, such as in the winter.
It is recommended to wait until a hen has actually laid an egg to begin giving her oyster shell supplements, as providing them too early can damage a young pullet's kidneys. Hens usually start laying at about 20 weeks, so oyster shell supplements can be introduced at this time. However, it is important to note that not all hens will need oyster shell supplements, as it depends on their individual needs. If a hen is getting enough calcium from other sources, she may not need to eat oyster shells.
In addition to oyster shells, there are other forms of calcium that can be provided to hens, such as limestone or crushed eggshells. However, it is important to bake eggshells first to kill any bacteria and crush them finely so that they do not resemble egg shells, as this could teach hens to eat their own eggs. Overall, by providing oyster shell supplements and other sources of calcium, you can ensure that your hens are getting the calcium they need to stay healthy and produce strong eggshells.

Oyster shells should be baked to kill bacteria and crushed so they don't resemble egg shells
Oyster shell supplements are an important component of a laying hen's diet. They are high in calcium, which is essential for laying strong eggshells. While most chickens benefit from oyster shell supplements, not all require them. Hens that do not yet lay eggs, for example, may not need oyster shell supplements.
Oyster shell supplements should be introduced when a hen starts laying eggs, at around 18 to 20 weeks of age. It is important to wait until the hen has laid an egg to begin giving them oyster shell supplements, as providing them too early can damage the young pullet's kidneys.
Oyster shell supplements should be baked to kill any bacteria and crushed so they don't resemble eggshells. Baking oyster shells at 250°F (121°C) for 10 minutes will kill any mold or bacteria lingering on the shells. Baking also dries out the shells, making them easier to crush. After baking, the shells should be crushed into bite-size pieces, no larger than your fingernail. This can be done by stuffing the shells into a bag and using a hammer to break them up. Alternatively, the shells can be ground into a powder using a food processor.
Once the oyster shells have been baked and crushed, they can be placed in a feed container inside the coop for the hens to eat as needed. It is important to provide oyster shell supplements in a separate bowl from the hen's food, as mixing it with their food can encourage hens to eat their own eggs. Hens will instinctively know to take oyster shell supplements when they need them, so it is important to make them available all year round.

Frequently asked questions
Oyster shells should only be given to hens that are laying eggs. Most hens start laying at around 20 weeks, so it is recommended to wait until your Silkie chicken has laid an egg before giving them oyster shell supplements.
Giving oyster shells to hens that are too young can damage their kidneys. Oyster shells are a source of calcium, which is needed to make eggshells. If your Silkie chicken is not laying eggs, it will not need this extra calcium.
Oyster shells should be placed in a separate bowl from their food. Hens will instinctively know to eat the oyster shells when they need to, so it should be available to them all year round.
A lack of calcium can cause hens to produce weak or irregularly shaped eggs, or to slow down their egg-laying. Hens that are low on calcium may also display behavioural problems, such as increased pecking and activity.
