I set off a few days specifically for training Lucy, simply to let Dudley watch, since it seems like our training sessions were going nowhere. Now, I picked up again on his training sessions, and it seemed that watching Lucy has helped him. He learned that the clicker means reward, and while he's still iffy with the target, he's not as afraid of it as he was originally, and will bite it, after a few seconds of backing up and staring at it. I'm so happy, because it seem that we're finally getting somewhere.

The only real problem we're still having is of the treats. I can't use anything too small, because if it's close enough, he'll go for the hand rather than the food (he does that on purpose). He likes millet from the spray, but if anyone holds it to him, he automatically hates it.
Does anyone have any suggestions on what I could try with treats? He seems to grow tired of having the same treat after a while, as opposed to Lucy, who could take sunflower seeds all day, and will still not grow tired of them. For anyone who have any larger-beaked parrots, what do you use for treats? I need some ideas for a "training mix", since he doesn't like receiving the same thing all the time.
