Abdullah, I am sorry if I sound negative all of the time. I know you have good intentions, but just hear me out. I am telling you this because it is important for both you and the bird:
If you attend school and your dad smokes, then does that mean the only attention your bird is going to get is when you are doing homework in your room with the door shut? If so, the bird will not be getting enough attention. Proper socialization is KEY---especially if you ever want to have a family of your own- This means teaching your bird how to act around people besides you (and teaching those people how to act around your bird).
Your bird will live a very long time. During this time, you may become a college student, a husband, a father....I know that your goal right now is to protect the bird from your dad's smoke and to keep your little brother's/sister's/cousin's fingers attached...THAT IS ALL SUPER IMPORTANT, I AGREE....
The thing is, if you don't expose your bird to other people (besides you) and if he only gets a tiny bit of attention (1-2 hours a day), he will likely be a very fearful and potentially territorial/aggressive bird.
I spent a lot of time with a mini-Macaw who wasn't too fond of me (tolerated me) but the worst bites I have ever gotten came from him---drew blood very easily. I still had to go back day-after-day and keep trying (biting eventually decreased), but it is very hard to calmly attempt to pick up a bird when the cuts from the previous incident have not healed. The bird will pick up on any nervousness and retreat from you further...
Imagine that 15 years have passed and you have a child of your own---a 2 year old girl---the love of your life. One day, she sneaks into the bird's room. At this point, the bird is already upset and jealous about the attention that you have been giving to new "flock members" and he perceives your precious little daughter as a threat (having never been socialized). Despite warnings, your curious child tries to pet the "birdy" (yeah, you told her not to, but like a parrot, 2 year olds don't often listen)...So, in go her tiny little fingers and CHOMP. Your daughter screams, your parrots screams, you run in and see blood so you scream...Your wife hears and runs in. In a panicked rage that her daughter has been hurt, she screams at you and the bird, grabs your daughter and slams the bird door shut, yelling, "I told you that stupid bird was dangerous and NOW LOOK!" In the car, she continues to rant about how "that bird has been a problem since day one". At the emergency room, your daughter gets stitches and a cast on her broken and bloody finger---the doctors say she was lucky it didn't snap off completely. Now, your family hates the bird even more than they did before, and they see it as a dangerous animal. You are angry because you made a promise to care for it, but now you have a daughter and a wife who you love more than you knew possible when you adopted your bird as a teen. What would you do? It is easy to say that you would continue to care for the bird, but many husbands make compromises to preserve their marriages...It is really impossible to say WHAT you will do at your current age, but I can tell you that a sickening number of parrots are re-homed due to shifts in family dynamics (wife/kids etc)...
My point in all of this is to say that currently you have 2 choices:
1. Keep the bird hidden away in your room in order to protect it from your father's smoke and small children.
2. Socialize the bird and risk killing it with fumes from smoke...and risk bites to others who may be less understanding.
When you are REALLY ready to own a parrot, you will not have to choose between these options and having to choose will not be fair to your bird.
You will be happier if you wait until you have your own place and until you can socialize the bird on your terms. I know you want this really badly....I commend you for coming on here and asking for help. I am stubborn like you and I get it---YOU REALLY WANT THIS----but you have to ask yourself what is best for the bird.
Lets say you are 15 now. What happens if you go to college or want to travel abroad? What if your bird never really bonds with you?
I really hope that at the end of all of this, you look at it from the bird's perspective.
CHALLENGE TIME:
1. Put a 4 ft by 4ft a box on the floor with tape.
2. Inside of the box of tape, you may bring a few items (NO PHONE-nothing else):
A. a food that you dislike (represents pellets),
B. One healthy snack, like an apple (represents fruit/veg),
C. a Rubiks cube (represents bird puzzle toy)
D. a few sticks of gum (represents bird chewing toys) and
E.A fidget spinner (represents other bird toys).
3. sit in your room, inside of that box (with the door shut). You cannot leave the box even if you hear things going on outside of your door.
Try it....see how long it takes before you start to go insane..I will be impressed if you make it 2 hours.
A bird like yours will spend 8+ hours alone in a box while you are at work or school.
This experiment still isn't perfect because there is no way for you to simulate the pent-up energy in a bird who is meant to fly miles each day---humans just don't have that kind of energy....
Oh, and imagine that you have to see the same person everyday and that you never get to interact with anyone else or see anything but the 4 walls of your room....for years and years and years....
Is this fair? Could you handle it if the shoe were on the other foot?
