Offer a wide variety of food keeping it in as natural a state as possible as it will provide the bird with entertainment as it eats. For example, for larger birds, feed corn on the cob rather than feeding kernels of corn in a dish. Wash all fruits and vegetables thoroughly before feeding. Because fruits and vegetables are high in water content, the urine portion of the droppings will increase. Any fruits and vegetables left uneaten should be discarded daily so spoiling is not a problem.
Sprouted seeds are a favorite especially among the smaller birds.
Good seeds to sprout include radish, rape, lettuce, mung beans, and milo. Offer sprouted seeds for only several hours at a time as they are wet and bacteria and fungus can grow on it in a short time. Be creative when preparing meals. Be creative in feeding also. Hang food from the cage top or sides, weave food into the bars of the cage, or stuff food in the spaces of pine cones.
