Lets not turn this into a debate everyone. I don't think that's what the poster wanted. As I've always said, somethings work for some and other things work for others. Since we're all different and such.
However, it is obvious this person feels bad for what they've done and came here out of remorse wanting advice and help. I do not think that this poster MEANT to harm their bird. It was a reaction. A negative one yes, but a reaction nonetheless.
What we have done already is give this person good advice on patience, calm and understanding where they went wrong. No need to talk about which modes of reinforcement work and which do not.
