All of this nutritional content is important to the well-being of chickens. (1)

To learn more about these healthy snacks, below are some of the health benefits of brussels sprouts for chickens:

1. Rich in Antioxidants

Brussels sprouts have an impressive amount of antioxidants and amazing health benefits. (2)

This green vegetable is especially high in kaempferol, which is an antioxidant that has many health-promoting properties.

Some of these properties include reducing inflammation and promoting heart health, thus reducing the risk of heart failure.

Antioxidants are compounds that help prevents free radicals from destroying the cells in the body. 

By feeding sprouts to your chickens as a healthy treat, you’ll help supply the antioxidants that their body needs to promote good health.

2. High In Fiber

Brussels sprouts are high in dietary fiber content. Fiber is an important part of a chicken’s health, especially its digestive system.

Lots of fiber helps promote regular bowel movements and helps food move along the digestive tract smoothly.

Besides promoting a healthy digestive system, fiber can help reduce the risk of heart disease and improve blood sugar control.

3. High In Vitamin C

When it comes to vitamin C, fruits such as oranges, grapefruits, and other citrus fruits are known for having a lot of this vitamin.

However, do not discount brussels sprouts. While sprouts aren’t fruit, this type of vegetable is loaded with vitamin C as well.

Vitamin C is one of the essential vitamins that are important to chicken health, as it does many good things for them. For one, it helps grow and repair tissues in the body.

Another thing vitamin C does is prevent chickens from getting sick. If they do get sick, vitamin C can help build their immune systems to get them healthy quickly.

Can Chickens Eat Brussels Sprouts Leaves?

Chickens can eat the leaves of brussels sprouts because they are edible and full of nutrition.

Before feeding them these edible leaves, you should cut or dice them up first. They tend to be tough and make it hard for the chickens to eat.

Another option would be to cook the leaves first to make them softer. However, the leaves will lose some of their nutritional value when cooked.

Can Chickens Eat Brussels Sprouts Raw?

Like other raw vegetables, chickens can eat brussels sprouts that are raw, but they can be a bit hard for them to eat.

For raw sprouts, the best option is to feed them cooked. Cooking will cause the sprouts to become soft, which will make it easy for the chickens to eat.

Another option is to chop or dice the raw sprouts up into small pieces.

Chickens are not picky eaters and will eat just about anything you give them. Just make sure the raw sprouts don’t pose any choking hazards to your chickens.

How To Feed Brussels Sprouts To Chickens

Chickens are great animals to keep and raise due to their ease of feeding. Unlike most other animals, chickens will just eat about anything that’s thrown in front of them.

When it comes to brussels sprouts, they eat them whether they’re cooked or raw.

However, raw sprouts are too tough for them to eat whole. You’ll need to chop them up first so they’ll be easier for your chickens to eat.

Below are some of the options you have to feed sprouts to your flock.

Raw Brussels Sprouts

Feeding them raw sprouts provides them with the most nutrition. However, in their raw form, they can be really tough for chickens to eat.

The best option is to chop or dice the raw sprouts, making them as small as their feed. You can feed the chickens just the raw sprouts or mix them with their feed.

Cooked Brussels Sprouts

Brussels sprouts that are cooked will lose some of their nutrition, but they will be easier for your chickens to eat and digest and still remain a healthy treat.

Cooking the sprouts will make them soft. You can feed the cooked sprouts whole or in small pieces.

Feeding them the whole cooked sprouts will keep the chickens active for a long time. The chickens will peck at the sprouts and eat them a little at a time.

Mixing Brussels Sprouts With Chicken Feed

This method is great for adding a nutritional boost to the chicken feed. You can mix the feed with raw or cooked brussels sprouts.

Make sure to cut the sprouts into small pieces first. Try to make the sprouts the size of the pieces of feed. Then mix it with their feed and place it in a bowl.

The chickens will eat their feed and the sprouts together and will not know a difference.

How Many Brussels Sprouts To Feed Chickens?

Brussels sprouts don’t have any toxins and they’re loaded with nutrition, so you really can feed them any amount without worrying about giving them too much.

However, due to the sprouts not having all the nutrition that chickens require, it’s best to feed them as a healthy treat and not as their main food source.

Brussels sprouts and other vegetables should make up 10% of a chicken’s entire diet. The rest should come from a quality commercial feed.

Therefore, it’s best to feed sprouts to your chickens in moderation.

Also, you should try to rotate other vegetables throughout the week, too. That way, the chickens will get additional nutrition that brussels sprouts don’t have.
