Ye Marie, I had his wings clipped because the first time he came out to grab a little piece of apple on the door he then went to the top of his cage and had no idea how to go back in and so he freaked out, started flying everywhere and wouldn't leave a high chandelier... I'll definitely let them grow now that he's more confortable with my presence.
I agreed with the bird buddy more because he could have more of a role model. I've read that budgies with 1 month of lots of love and attention get tame which is great. I do understand what you're saying though, could Oscar get jealous? I don't know...
And yes I did start target training him like 2 months ago (I wrote this above

) and had a bit of success but not nearly as much as I expected. He often comes for the target stick but normally I always have to cheat the first treat or two and the the target a bit closer to him, no more than this though or he'll get used to that. Other than that there's not much else we achieved with target training, except for two times which I got him to put one of his feet on a stick I was using for stepping up for support, not that bad but it was really just 2 times in hundreds.
Cheers
