I wouldn't mist him every day. He doesn't need it. Once a week is enough. I know others do it a lot, but my greys hate it, and I don't force it . They take their own baths when they feel the need, or if I see them getting dusty, or starting to itch, I will mist them.
You have only had him home 10 days, it's too soon to expect anything other than him trying to adjust to his new cage,house, family, toys, etc. Just let him take the lead. Once he feels more comfortable and somewhat trusting, he will respond to you better. But it sounds like he's quickly on his way already!
