Well Katsnkeets, if you are only worried about him/her being noisy at night....No they are not noisy at night once they are covered. After they're covered you might hear some light chitter chatter as they talk themselves to sleep, but that's usually it til morning.
BUT they can be quite noisy during the day, I think more so if more than 1 keet is involved because they talk to each other a lot. I don't mind their chatter, I actually enjoy it, but other members of my family get annoyed by it sometimes.And the louder people talk or the louder u turn up the tv..the louder they get to compete with it! LOL
Noise is not the only thing to think about tho. Keets are a lot more work to take care of than people think. Much more involved than say a cat or a dog.They need lots of time and patience from you if you want it to bond with u and ur family. Once you have earned its trust tho, they are AMAZING and sooo much more fun and interactive and SMART than they get credit for. They love to play and interact with their people flock.
Cage has to be cleaned daily, food water changed a couple times a day. They need veggies..washed, chopped,or clipped to side of cage...they need cooked foods...and LOTS of attention to be friendly, happy,healthy, and well adjusted. SO if you are only 15, a lot depends on if you are one that spends a lot of time at home..or if u are one that is on the go all the time and not home much. AND you have to make sure your parents are willing to cover vet costs when needed and buy food/pellets/toys/vegs..all the things they need if you aren't able to but them.
I do have to say that your dad is wrong...they are NOT demon birds!! LOL Quite the opposite in fact if they are shown lots of love and patience. They're a blast to watch, they love to play fetch etc with cat toys or whatever, they fly around like little kamakaze pilots once they get the lay of the land, they learn all sorts of things you'd never expect. I have found they are sooo much more than I ever expected!
So if you think you can meet all their needs..go for it. It will certainly help tho if mom and dad are on board with it all too!
Budgielover, You gave some good advice and pointers, sounds like you really love your birds and try to do right by them..but there are at least a couple I HAVE to comment on.
#15-keets need grit??? Parakeets DO NOT need grit!!! As Tweetymom pointed out it is now known that grit is actually BAD for them. It can cause crop impaction. So if you give your bird(s) grit..take it away from them!
And #10? The seed mess? They DO cause a mess..but nothing that can't be vacuumed up LOL What exactly do you mean by "the parakeet will just chew on it til gone??? They do NOT eat the hulls..and if yours do then I have no idea why! Are they getting enough to eat?? Seed hulls have to be blown off the top of the seed cup to see how much actual seed is left for them to eat. I don't know if they will eventually try to eat the hulls to if they have nothing else to eat? If you are not seeing lots of hulls then something is not right. hmmmmmm
