Beans can be a dangerous food for chickens if not prepared correctly. Raw or undercooked beans contain a compound called lectin which is highly toxic to chickens and can cause severe digestive distress or even death. As few as a handful of raw beans can be fatal to a chicken, making them a food to handle with great caution.
In summary, while cooked beans can be a healthy snack, raw or undercooked beans are highly toxic and should never be fed to chickens. Always prioritize safety and stick to prepared treats to keep your flock healthy and happy.
