I'm happy with just my senegal. Sure, there are other bird's I'd love to have, but I am a fairly busy person (full time job, and I'm 20 and have a decent social life). I always put Pixel first in my schedule; I'll turn down plans if it means she won't get her fair share of my attention that day, that or I invite people over and have her with us while we visit (my friends all love her so that's a perk). But, I quite frankly do not have time for another bird. Wouldn't be fair to Pixel.
I think it's great you make your bird such a priority when you could be spending your time doing other things.
The whole point of a dream flock is that if all the circumstances were right (meaning nothing standing in your way; money, time or otherwise) this is what you would have. No one can say for sure weather it will ever happen because life changes so much.
If your dream 'flock' consists of one bird than that is fine. I just wanted to tell you the point of this thread is that time wouldn't be an issue for you.
