I'm so sorry you are having to rehome your bird.
All of the stickies in this forum are good ones, they are the ones at the top in pink.
I would suggest reading through them all, and hopefully it will give you some tips on how to make sure the home they are going to is a good one.
I wish the best of luck to you.
It will also help if you put your general location. Many birds have gone to wonderful homes with other forum members.
