Alright so i have offically decided to egt another cockatoo. Since I am going off to school in about 2 years and my parents won't let me take Miley I want a more one person brid to take with me, but sitll be as cuddly and funny and adorable as Miley is right now (lets see how she is in 2 years eh

) But I am havign a bit of decision to make.
I have looked at all types of birds, seeing if an amazon, macaw, grey, conure, etc etc would be better for my situation. But aftre spending 2 months at the rescue I don;t much care for a macaw, and amazons dont interest me much you know? And I had a grey and it really didnt fit ym personality and what I want out of a parrot so I could give it all the time it needs. I wont be getting a bird until afetr summer when I have more time but I decided a cockatoo would be best for my situation. Now which type?
I want a rehomed bird ebcause I fell in love a few at the rescue, I thought they would have more cockatoos but they only have about 5 at most out of 50 birds. So goffins I think are adorable and I would love one, and bare eyes are amazing too! I like lesser's and galahs are great to, I think I dont want a big cockatoo because that would scare my grandma and shes who i will be living with. So I researched all 4 and asked rbeeders, owners, and the nancys(recues owner) opinion and still have no idea, so now I thought you guys could help! which too would be best?
Noise isnt an issue because my grandmas almost death and she has a house, someone will always be there for the bird so time isn't that big either, although when i'm done school and move out the bird might have to be alone for longer then used to, so i guess that should be taken into concideration. A good talker would be ncie but not nessary, and space and cost isn't an issue either. I got the 4 choices, galah, lesser sulphur crested, goffins and bare eyed and not one is at the rescue so I don't have a first hand expirance with any of them so i'm relying on you guys for your good points and thoughts! Thanks in advance!
