1. NO AVOCADOS:
Avocados are a popular fruit, but chickens should not eat them. They contain a toxin called persin, that is harmful to chickens and other animals.
The flesh of the avocado is safe, but the skin and pits can cause serious issues.
If chickens eat the skin or pits, they may have trouble breathing and fluid can build up in their chest. In severe cases, this can lead to death.
Some people think that chickens can eat avocados if you remove the skin and pits. You need to decide if the risk is worth it.
2. NO CHOCOLATE:
Chickens should not eat chocolate for a few reasons. First, chocolate is poison for chickens. The caffeine in chocolate can harm them.
Second, chocolate has too much sugar and fat, which can make chickens gain weight.

Chickens should not drink coffee or tea, including coffee grounds and tea bags. Caffeine is bad for their health. It can raise their heart rate and make them dehydrated.
This includes all types of coffee, both regular and decaf, as well as black and green tea. Caffeine is dangerous to chickens.
Don’t feed leftover coffee grounds to your chickens. Instead, use them as garden as fertilizer!

4. NO ALCOHOL:
The moldy grains can produce harmful toxins. Alcohol is created during fermentation and is a toxin that can be deadly to chickens.
Even small amounts of alcohol can cause major health problems in chickens. This includes beer, wine, spritzers, hard cider, and all hard liquors.
Chickens that consume alcohol indirectly through fermented grains may also have difficulty laying eggs.
Be very careful of feeding damp grains to your girls, as eating fermented grains can also lead to digestive problems, such as diarrhea or death.

Chickens should not eat onions for a variety of reasons.
- Onions have a compound called allium in them. This entire family of vegetables, like onions, includes garlic, leeks, and shallots. These are all part of the allium family.

- Third, onions can irritate a chicken’s eyes and respiratory system.
The no-onion list includes white, red, and yellow onions along with no green onions.
6. NO GARLIC:
Garlic is one of those foods that hangs in the balance. Some people advocate feeding garlic to chickens, believing it will make them healthier and others do not.

Like onions, garlic belongs to the family of plants that contain allium, which also includes onions and leeks. These plants contain compounds that are toxic to chickens.
While a small amount of garlic may not be harmful to chickens just make sure to monitor the amount. As the rule of thumbs goes, when in doubt leave it out!

8. NO RAW FISH & MEATS:

2. Raw meat and fish spoil quickly at room temperature, so in the chicken coop they will spoil that much quicker. It is advised not to feed raw meats.
2. If chickens do eat raw meat or fish, they should be monitored closely for signs of illness and treated promptly if necessary.
9. NO MOLDY & SPOILED FOODS:
Chickens will eat almost anything they find. They are omnivores, meaning they eat both plants and meat. However, not all foods are safe for them.
Some foods can hurt chickens, such as moldy or spoiled food.
Moldy food can have harmful bacteria, especially old bread. Check for mold spots, as the mold can spread deeper than what you see on the surface.
Understanding how mold invades and grows on bread is a must! Moldy bread is something no one should eat, including your chickens!
So, all moldy bread should surely go into the compost pile, as this bacteria can make chickens sick and even kill them.
Fresh and clean food is important. Your eggs will taste better when your chickens eat good, clean food.
If you suspect your chicken has eaten bad food, watch for signs of illness. Common symptoms include tiredness, diarrhea, vomiting, and possibly death.

Green potato peels have high levels of solanine, which is a poison. Signs of solanine poisoning in chickens include stomach upset, dizziness, weakness, and paralysis. In severe cases, it can lead to death.
If you think your chicken has eaten green potato peels, contact your veterinarian right away.
To be safe, avoid feeding your chickens any green potatoes or green potato peels.

To keep your chickens healthy, feed them balanced chicken feed, fresh fruits and vegetables, and provide plenty of water.
