Hi Haydn,
You will always see a wide range of amounts fed. Birds eat to satisfy their nutritional needs, and when being fed a nutritionally balanced food like Nutri-berries, a bird generally will not over eat. The amounts can vary greatly based on each bird’s metabolism & activity level, as well as other foods it consumes, and lastly, how much it wastes. Most birds eat anywhere from 6-12 per day. But one bird might eat 99 percent of each berrie while the other wastes as much as half of each one. If she wastes a lot, give her less at one time, and pick up any wasted crumbles and return them to her bowl as long as they didn’t get soiled. Being a cockatoo, she probably does waste some, but she’s also one of the smaller, higher energy cockatoos, so she needs more calories than a less active bird. Again, since the food is balanced nutrition, she isn’t going to eat more than she needs.
Thank you for asking Lafeber,
Brenda
