What if the bird does not eat any of the pellets or extruded pieces?
Try to encourage the bird to eat these items by hand feeding them until they are acquainted with this ingredient. You can also control the amount of food being offered to encourage the bird to eat all the food that is available. Often people offer more food than is necessary for a bird to eat in one day. This allows the birds to pick and choose the items they prefer and leave the rest. Cutting back on the amount being offered will encourage the bird to eat all the food. However, always watch the bird to make sure they are eating enough food.
