Keep reading to find every aspect of the question: Can Chickens Eat Moldy Bread?

Is Mold Bread Safe For Chickens?

Is Mold Bread Safe For Chickens

Before I explain further, let me first clarify what mold is— fungus that thrives in moist, warm settings. Bread gets moldy when it’s exposed for a long time to elements that make it wet. It usually takes 7-10 days for bread to mold.

Stale bread is not moldy bread. Mold releases poisonous spores that are harmful to humans and animals, both. These spores produce fuzzy green, black, white, or pink spots that are visible to the naked eye. Due to these spots, the bread will also have a strange odor if it’s moldy.

While feeding moldy bread to the chickens might seem like an idea that could save the day, in reality, it ruins the day. That’s because, when I say harmful to humans and animals, both, chickens are included!

Eating moldy bread, or moldy food in general, can have a variety of adverse effects on a chicken’s health. The spores may irritate the respiratory system, and the bird may develop respiratory problems as a result.

Moreover, mold produces mycotoxin, which is harmful to all animals and humans. Consuming moldy bread automatically translated to mycotoxins exposure, and that translates to liver damage, immune system suppression, and even death.

It may also upset your chicken’s stomach and cause diarrhea, which will lead to substantial loss of fluids and dehydration. Also, since moldy bread causes a chicken to get sick, it will also result in loss of appetite or decreased appetite, leading to malnutrition and weakness.

In severe cases, moldy bread consumption can even cause neurological damage, and your chicken may experience seizures! That said, it is not safe for chickens to eat moldy bread. Unfortunately, that’s not all!

When a chicken consumes moldy bread, the toxins in the bread will not only enter the chicken’s body but will also transfer to your chicken’s eggs!

Since egg production will be affected, the quality of the eggs will significantly reduce, and if the toxins are in heavy amounts, the egg will not be fit for consumption.

Also, if you keep the moldy bread with other food that’s meant for your chickens, it will also get contaminated. And then, all of it will become unfit for your chickens. Plus, let’s not forget the treatment costs that the entire ordeal will bring if your chicken gets sick.

So, not only does it put your chickens through pain and discomfort, but it will also bring you a lot of inconveniences. As guilty as you may feel when throwing the moldy bread away, discarding it is the only safe option.

Things To Lookout For (Symptoms)

Things To Lookout For

It’s possible that your chickens eat moldy bread or moldy food by accident. So, it’s important to be vigilant and always stay on the lookout for any symptoms. The number one telltale indicator is when the chicken loses its appetite abruptly.

Another warning sign is when your chicken starts acting in ways that it wouldn’t act normally. For example, if your chicken becomes too lethargic and sleepy, or extraordinarily energetic and restless— there’s something wrong.

Lastly, if your chicken urinates excessively, gets diarrhea, or experiences any other digestive issues, it is a symptom. That’s because mold often upsets the stomach and the digestive system. In case you notice any of these symptoms, get a vet involved for an accurate diagnosis.

How To Tell If Your Bread Is Moldy

I’ve already explained what Moldy Bread looks like. Mostly you can tell by looking at the bread that it’s moldy. But in some cases, you might need a bit of help. Always inspect a bread loaf before giving it to your flock. Take a close look.

If you notice fuzzy or slimy patches on the surface of the bread, discard the bread loaf immediately. The patches can be either green, black, white, pink, or all of these colors. Next, check if the bread is too hard.

Some breads like rye or sourdough may naturally have a tougher texture, and that’s OK. But in cases of normal bread, it’s an indication of mold. You may also want to smell the bread but don’t bring it too close to your nostrils as it can be harmful.

If the bread smells strange, it may be moldy. Lastly, cut the bread loaf so you may examine it from the inside. Sometimes, mold does not appear on the outer surface but grows on the inside.

If you spot even the tiniest mold spot on the bread, throw it away entirely because mold spores disperse at a fast rate. It is likely that by the time you have discovered the mold, the whole bread loaf is contaminated even if you don’t see visible signs.

Remember, it’s always better to be safe than sorry!

Can Chickens Eat Bread?

Can Chickens Eat Bread

It is a common belief that bread is a safe-to-eat food for hens. In fact, isn’t that why you considered feeding moldy bread to the chickens in the first place? Bread crumbs are often fed to chickens as treats. But, can chickens eat bread?

The answer is yes! Just because moldy bread is harmful to them doesn’t mean you stop treating them to bread altogether! It only means that you should be mindful and analyze the bread thoroughly before feeding it to them.

You can even make it fun! Mix the bread with their regular chicken feed and add water to it, and throw in some vegetables like squash, pumpkin, or broccoli. This way, you’ll be able to treat your chickens to a nutritious but tasty snack. You can try different vegetable combinations, too.

Also, if baking is something you like, you can also try baking different types of bread for your chickens. Add different items to the bread batter like berries or nuts to the bread, and you will have your very own special chicken bread.

It’s also important to note that bread is not good for baby chicks, as they need proper nutrition for growth. Also, you should always ensure that the bread is fresh and that you do not give it to them daily! It should be treated only as a special treat that you give to them occasionally— too much bread can be unhealthy.
