Raising Worms for Chickens

by Sam Richards | Last Updated: January 28, 2021

While raising chickens, you might notice the occasional dip in egg production. When you see the chickens acting lethargic and not moving around much, you know it’s time to supply them with some protein. But it is not an easy task to find healthy snacks for your flock. Most of the products you find at the store contain unnecessary ingredients and harmful additives.

Why Should You Feed Worms to Your Chickens?

Mealworms prefer to live in dry and dark areas, nibbling on things like grains, cereal, and flour. You can easily grow them at your home with minimal upkeep. Some of the benefits of feeding worms to your chickens are as follows:

Raising Your Worms

Now let us look at the fundamentals of raising a worm colony. But before starting this operation, you need to know about how mealworms grow and procreate.

Worm Ecology

Mealworms are the larval stage of darkling beetles. A female beetle lays several eggs at a time, and after two weeks these eggs hatch and give birth to the worms. They will remain in this stage for almost three months before transforming into pupae.

While raising worms, you might sometimes mistake the pupae for dead worms so it is important to check if they are alive. You can do this by disturbing the pupae, upon which you will see them twitching. The worms do not eat for three weeks at this stage, and afterward, they turn into adult beetles. It takes about six months for the worms to turn into adult beetles.

Now, let’s look at the different steps involved in raising worms:

1. Identifying the Location

Firstly, select an elevated spot that won’t get flooded during rain. You should make sure you can access the place using a wheelbarrow so you can collect the compost whenever you wish to.

2. Preparing the Hole

For a worm bin, you can take an area of 3 x 6 to 4 x 8 feet with a depth of 1 foot. Such a bin will be able to absorb a large amount of organic waste and make it possible for you to grow worms in the thousands. A screen door is perfect as a lid, and you have the following options in this regard:

3. Building the Worm Bin

After digging the hole, you should place a lining of solid frame on the interior as support, so that the dirt walls don’t cave in. Concrete blocks have the perfect dimensions for this purpose, but you can use planks made of red cedar or heartwood as well. However, you must use pressure-treated wood since it is resistant to rot. If you use untreated wood like oak or pine, you will need to change them after a few years.

No matter what type of wood you use, three planks of 8-foot length should be sufficient for a worm bin with a dimension of 4 by 8 foot. You can cut one of the planks by half and create the frame with the help of screws or nails. After this, you can drop it into the hole you dug.

4. Adding the Lid

After digging the bin and installing the frame, you should add the screen door as a lid. You can add hinges on one side and install a handle at the opposite end so you can open it easily. Following this, you need to place the soaker hose close to the door, securing it using fence staples and fence wire. For propping open the lid, a small scrap piece should be ideal.

Remember, it is important to protect the interior of the bin from direct sunlight, so you can use a piece of shade cloth or durable landscape fabric to cover the entrance. This will also allow some rainwater to seep into the bin. At the same time, you must make sure your worms don’t drown when there is heavy rainfall. Hence, the bin ought to be covered with plywood, tarp, or metal.

5. Adding Water

In order to add water to the bin, the soaker hose should be connected to the rain barrel using a spigot and a garden hose. Since you’ll be adding dry materials to the bin, the soaker hose can ensure an optimum 80% moisture level is maintained. In case there is heavy rainfall, you can turn off the supply of water using the spigot.

6. Adding the Worms

Now comes the time to add the worms to the bin. Experts suggest using 1 pound of worms for each square foot of the bin. This will create the optimum conditions needed for composting. You should aim to raise more worms with as little waste as possible so that your chickens always have a steady supply of protein.

7. Feeding the Worms

Of course, you need to make sure your worms are well fed so that you can fatten them up for your flock. At an interval of a few weeks, you should supply the worms with substrate or food. Take some feed and add it to the tank while making sure the depth is not more than 3 inches.

It is not necessary to feed them certified worm food. If you have leftovers from your kitchen like discarded vegetables and fruits, you can use them as well. It is important to note that the worms take a bit of time to go through kitchen scraps, so you need to be careful about your bin being filled with spoilt food.

Some of the things you can feed your worms include:

Make sure there is no mold or mildew inside the worm bin.

8. Harvesting the Worms

The amount of time required for the mealworms to be ready for harvesting depends on the conditions under which they are raised. But normally it takes a few months for them to mature. Make sure you don’t feed your chickens the beetles or the pupae. Leave them inside the container so they can reproduce.

If there are dead beetles inside the bin, it is not a cause for concern, since the worms will clear them out. You only need to remove any fungus-infected food or mold. It is best to wear gloves while you are harvesting the worms to avoid contamination.

Mealworm bins often produce dust and some people with respiratory problems may be sensitive to this. So just to be safe, you can wear a mask to prevent any irritation or allergy. An easy way to extract the worms is to introduce some food into the bin. The worms will be attracted to the piece of fruit or vegetable, after which you can take it out and put it in a different container.

Make sure there are enough worms inside the container that your chickens can feed on. Optionally, you can keep the vegetables as well, as they might enjoy eating those. If there are excess mealworms, you can always put them inside plastic bags and freeze them to extend their lifespan.

How to Feed the Worms to Your Chickens

By combining worms with a decent carbohydrate source, such as grain, you can give your chickens all the nutrition they need. Start with small amounts first to make sure the chickens are feeding on the worms. Start with feeding each chicken half a cup of worms, after which you can adjust the portions as required.

You can also have the worms dried and mix them into the chicken feed, but this leads to the loss of some vital nutrients. You can dry them by placing them out in the sun or by using a dehumidifier or a convection oven.

Conclusion

Growing your own worm colony is a more cost-effective way to feed your chickens compared to purchasing feed from the store. Soon you will notice the overall health of the chickens improving, so you can get better quality eggs from them.
