Don't be sorry for having a little rant Summer - most all of us here feel the same way!
I often have alook on preloved and similar sites over here and it's just so sad.
I have to say as well, when I was looking into getting a grey, not one person I spoke to, breeder or otherwise, mentioned any of the mess, noise, bites, attitude or a million other little things I've discovered since getting Alfie. I think all these things should be disclosed up front so any potential bird owner knows 100% what they are getting into!
Would it have put me off if I'd known? Absolutely not - well probably not, but it still would have been nice to have had both the positives and negatives beforehand.
