Toxic and Dangerous Foods for Chickens

Never feed: avocado pit and skin (persin toxin, the flesh in tiny amounts is debated but not worth it), raw or dried beans of any kind (phytohemagglutinin is lethal, cooking neutralizes it), green potatoes and green potato peels (solanine), raw potato in bulk, tomato and eggplant leaves and stems (nightshade family), rhubarb leaves (oxalic acid), onion and garlic in large quantities (can cause hemolytic anemia, small culinary amounts are fine), moldy anything (mycotoxins are one of the top silent killers), chocolate (theobromine), coffee grounds and tea bags (caffeine), heavily salted foods (chickens have no way to shed excess sodium), alcohol, citrus in large amounts (debated, most chickens ignore it anyway), apple seeds and stone fruit pits in bulk (cyanogenic glycosides), raw meat that has spoiled, dried or raw beans, uncooked rice in huge quantities (fine cooked). Also keep chickens away from lawn clippings that have been sitting and heating up, treated wood shavings (cedar oils irritate the airway), and anything sprayed with pesticide or herbicide within the last two weeks. If a chicken eats something questionable and acts fine within 24 hours, they almost always are.
