Hi Colt! In wanting a Goffin's Cockatoo, you're choosing a really fun, cuddly, beautiful bird to join your flock. They are super intelligent, comical, fun-loving, birds that have earned the nickname "velcro birds" because they love nothing better than to be with you. Mine is 9 years old, a male, whose name is Baby (when I got him, I was told he was a female, but DNA later showed that he was indeed a male). He's a lot of company to me, kind of like having a three-year-old, and I dearly love him. I'd never consider giving him up, not for anything in the world. He's extremely tame and very social, and he hasn't yet met anyone he doesn't like. However, I would be remiss if I didn't warn you about the negative side of owning a cockatoo, as well as the positives.
Cockatoos are very loud. If you live in an apartment, this is definitely not the bird for you. They can also be very destructive, stubborn, and are spoiled very easily. Baby has chewed the tops of all my wood dining room chairs, the corner of a shelving unit in my living room, my curtains, many of my magazines, my mail, and a $20 bill. He's now working on destroying the third venetian blind that I've replaced in one of my windows and has bitten holes in two others. You can't leave anything around for him to pick up, and I have to watch him every minute he's out of his cage. I don't dare leave him out of the cage when I go out. He occasionally terrorizes my two small dogs and doesn't at all like the idea that I have another bird (a Solomon Island Eclectus). He tolerates the Eckie as long as he's not getting too much attention from me while Baby is wanting cuddling. And did I mention loud? LOL! I've actually gotten him to cut out a lot of screaming by ignoring the screaming and only responding to him talking, but it took quite a while to do this. Baby also likes to try to take the screws, etc. out of his cage, and his toys don't last very long before they have to be replaced. Parrots are also very messy. I change Baby's water at least 3-4 times a day, as he likes to dip some of his food in water before he eats it. There's always seed on my living room floor, and I change the papers in his cage every night, and sometimes twice a day. Besides his poop, anything he doesn't like in his food bowl also gets tossed onto the cage floor.
I've retired, so am home with my birds most of the time. They receive all the attention and interaction they want. If I worked full-time, I don't know that I would have taken on the responsibility of the birds, as they really need a good amount of time out of their cages. A cockatoo is not a bird that you can feed, water, and leave in the cage all the time (really, no bird is). Without attention and interaction, he will resort to feather picking and possibly even self-mutilating. I haven't gone on family vacations because I can't find any bird people to watch my two while I'm gone. They're not fond of change, so I would never subject them to boarding at a vet or at anyone else's home.
I feed my cockatoo fresh fruit and veggies, Zupreem nut-flavored pellets, and a bit of Volkman seed in the evening. I also give some almonds, walnuts, or pecans in limited amounts. I add flax seed and chia seed to his veggies. He especially loves jalepeno peppers, corn, apples, and blueberries. Once a week, I hard-boil an egg and break it all up (shell included) and give him some of that. He also eats some of my meals with me, depending what they are and whether they're OK for him to eat.
I'm not telling you all this to change your mind about getting a cockatoo, but I do want to let you know what you're getting into before you get one. So many end up in shelters because the owner didn't realize all the responsibility there is to owning a parrot. My two birds are relatively young (9 and 6 years old) and have already had three homes each before they came to me. They bond with people and then find themselves in another home. It's not fair to them. My home is their last until I pass away and, since they will outlive me, I named someone in my will that will take them both.
To sum it all up, you have to be a bird person to take on the responsibility. And if you are, your cockatoo's negative issues will all be worth the love, affection, and bond you will have with your beautiful bird.
