Cooked green beans are safe; sources disagree on raw ones, so cooking them is the cautious choice.
Part by part
- YesCookedPlain.
- In moderationRaw/freshFresh Eggs Daily lists fresh green beans as fine; The Happy Chicken Coop says cooked only (phytohemagglutinin); Grubbly Farms says raw in excess is a problem (lectins).
Why
Green beans are immature Phaseolus beans; raw dry beans of this species contain phytohaemagglutinin, which UF/IFAS says causes severe digestive problems. Whether fresh green beans carry enough lectin to matter is not settled by the sources reviewed.
Watch out for phytohaemagglutinin (lectin) — concern mainly for raw beans. If a bird may have eaten a lot of it and seems unwell, call a veterinarian who treats poultry.

The treat rules for every food
- 1Scraps are not nutritionally balanced. Letting them displace complete feed can cause nutritional disorders and lower egg production; hens that fill up on treats can run short of calcium and draw it from their bones, weakening shells.
- 2Never feed moldy, rotten or spoiled food. Molds can produce mycotoxins (e.g., aflatoxin on corn, peanuts, nuts, rice) that harm poultry, and University of Kentucky notes mycotoxins remain even if visible mold is removed. Rotting food can also be a source of Clostridium botulinum (botulism, 'limberneck'). Stale or wilted (not moldy) produce and bread are generally considered fine.
- 3Avoid very salty, sugary, fatty, fried or heavily processed human food (chips, fast food, candy, heavily salted leftovers). Merck notes salt above about 2% of the diet is usually considered dangerous for poultry, that birds under 21 days old are more susceptible, and that restricted water access makes salt problems worse.
- 4Provide insoluble grit (granite grit or small stones) whenever chickens eat whole grains, scratch, seeds or forage; birds that can reach the ground usually find their own. Oyster shell is a calcium source, not grit (it is too soft). Birds eating only a complete pelleted feed do not need grit.
