Owning chickens comes with a lot of questions, especially diet-related questions. Chicken like to feed on leftover table scraps a lot, but it is advisable to feed them with moderation and as a supplement treat and not the chicken’s main course.
This is because, although table scraps are safe for your chicken to eat, most of them are very low in protein compared to commercial grower rations. If you have baby chicks, it is advisable to wait till they are 3 or 4 months before introducing table scraps such as onions to them as they require a lot of protein to grow.
Can You Feed Chickens Onions?
Many chicken keepers today struggle with the question of feeding them, what is safe or unsafe for chickens to eat, what is nutritious and in what quantities, and so on. As most animals don’t eat onions, there is a general assumption that chickens don’t either.
The idea that chickens don’t eat onions is just a myth, so yes, chickens can eat onions. However, the onions have to be in small quantities and only occasionally.
When taken in moderation, onions are a healthy feed for chicken because they are rich in minerals and vitamins. They are healthy for the chicken to consume as they help with the chicken’s bone health and colon. Onions are also responsible for reducing blood pressure and inflammation, so a few onions are good for chickens.
When taken in large quantities, onions can be harmful to chickens, causing hemolytic anemia. The edible parts of an onion are the flower, the stalk, and the bulb of either white, spring, or red onions.
Many people don’t know this, but chicken can really eat onions, which is a type of food that has been shrouded in mystery for years. In truth, all parts of the onion are safe for chickens to eat, but chickens should feed on onions in small quantities.
I found several scientific studies that suggest that onion and onion extracts are purposefully fed to chicken most times, which leads me to believe they are safe for consumption. I wouldn’t recommend forcefully feeding onions to your chicken, though, or mixing it with your chicken’s regular food, or using onions as the only major ingredient in your chicken’s diet.
What Does It Mean in Small Quantities?
As studies have shown, onions are safe for chickens to eat, but only when regulated and in small quantities because they contain some toxic compounds.
These compounds are toxic to most animals, including chickens, and they all respond differently as they do to other foods. Like humans, the toxicity of onions does not affect chickens or lead to health complications when taken in small quantities. However, you shouldn’t force onions on your chicken if they don’t like them; give them the option to pecking them when they want.
Chicken like to feed on table scraps, and most of what is left off your meals are safe for them to feed on. These table scraps, however, don’t form a balanced meal for your chickens. As such, it is advisable to feed onions to chicken as a complimentary treat and with moderation.
Edible Onion Parts for Chickens
The bulb is the most edible part of an onion, even for chickens. The bulb of an onion grows underground and is used by human populations in cuisines to spice up. They stalk, a white part that grows upwards, is also edible for chickens, as it contains nutrients that are similar to the bulb’s nutrients. It is safe for chickens to eat the bulb and stalk of an onion, but not the top green part of the scallions.
Regardless of which part of an onion you feed chickens, as long as you don’t cook it properly, the chickens might not like it very much. Chickens are not very fond of onions in a raw state or eat them exclusively without any treats to rid of the strong taste and smell, especially red and white onions. Chickens will mostly feed on the bulb if they are hungry enough and leave the stalk behind. Chickens lack teeth, so they cannot chew the stalk well, which makes it difficult to consume and digest.
Chicken can comfortably consume onion peels and with no detriment, but they leave the peels behind most times. Onion peels have no verified nutritious benefit to chickens, so they will be left behind when you serve them with freshly chopped onions.
What Happens When Chickens Eat Onions?
Well, what happens when you feed chickens onions is a question most chicken keepers have no answer to, but your guess is as good as mine. When chickens eat onions, especially if they are layers, their eggs have an onion taste, which is not very appealing to some people. A study done in 2001 verified that feeding onions to chicken would result in them laying eggs that emit an onion-like smell. As such, onions are very powerful and impactful when included in chicken feeds.
According to another study, feeding onion extracts to your chicken can add weight and improve their meat quality. This is especially if the chickens are broiler chicks. Feeding your chickens onions has different results, such as affecting the quality of the eggs and the meat and the nature of their manure.
Cooked onions are safe for onions to consume, but with the exception of onion rings as they are dry foods. Dry foods are not healthy for consumption for either you or your chickens, and the impact on the quality of eggs and egg production as well. Generally, onions don’t have a negative effect on chickens when taken with moderation and occasionally. Still, they make the eggs have a weird taste for broilers because they can’t digest the lipids.
Another study found that feeding green onions to geese is not safe. Green onions can cause anemia and lead to affected liver functionality. Onions are toxic to many animals, and geese are not an exception, but they are safe for chickens, as long as the chickens are an adult, and you give them the onions in moderation. If you feed your chickens too many onions and make them their diet source, they suffer from hemolytic or Heinz anemia, which results in chickens with lethargy, weak legs, and an unkempt look.
Typically, chicken feed on non-fatty foods, so it is common sense to avoid onions that have been cooked in butter or oil. If you want your chicken to enjoy their onions, cook them in a little water to soften them, or grill them. Despite onions being safe for chickens’ consumption, they have not considered the best treatment. Onions contain sulfides and sulfoxides, which cause anemia in animals by destroying the red blood cells.
What Quantity of Onions Should Chickens Eat?
As stated above, onions are safe for chickens to eat, as long as they are taken in moderation and in small quantities. There is, however, no fixed number of onions that chicken can feed on in a day, but it is vital to feed them just like you with do other treats, in small quantities as too much can harm the chicken.
When feeding onions to your chicken, you can cut them up in small pieces or just use leftovers from foods. Limiting the number of onions you feed mature chicken is okay, but do not force them to feed on onions if they don’t appear to like it. However, young chicks shouldn’t have any onion treats because they need proteins to grow, which isn’t present in onions. It is also easier for younger chickens to be affected by different treats due to their weak immunity and delicate digestive system.
Preparing Onions for Chickens
As stated above, onions are more appealing to chickens when cooked than in their raw form. They are also safer when cooked because the heat destroys most of the harmful compounds. However, it is not recommended to feed dry foods to your chicken as it affects the chicken’s health and the taste of their eggs. You can make them roasted onions, scrap mash onions, or onion trail mix, and the chickens will enjoy it if you don’t want to cook. It is okay to cut fresh onions into pieces and feed your chicken if they like it that way.
Are Onions Nutritious for Chickens?
Onions have some nutritional value for chickens, which is why they are considered a supplement treat. Onions are relatively low in fats, calories, and carbohydrates, but at the same time super nutritious as they are full of antioxidants, minerals, and vitamins (Vitamin C, folate, potassium, and Vitamin B6). Onions also contain other plant compounds such as quercetin, anthocyanins, thiosulfates, and sulfur compounds.
The antioxidants found in onions help reduce blood sugar levels and improve the chicken’s bone health. When raw, onions have less than 40 calories for every 100 grams with 89% water, 9% carbs, and 1.7% fiber.
The carbs from onions are mostly simple sugars, and the fiber has fructans that are good for the bacteria in the chicken’s gut that is used as fuel during digestion. When this happens, short-chain fatty acids are produced, which help reduce inflammation, and they are also good for colon health. This is important for chickens because onions prevent the bloat that is otherwise caused by these inflammation issues. Bloat means certain death for chickens unless they get a vinegar dose.
The carbs come in simple sugars form, and they provide energy to the chickens for them to be active throughout the day. The short-chain fatty acids produced are responsible for maintaining the health of the chicken’s colon while reducing inflammation at the same time.
