New conure owner ^_^

Hi all parrot luvers ^_^ I am the proud owner of a male hand raised fancy green cheek conure who is now two years old!......I ended up buying him when I had to leave a little pet store that I was working at due to moving. All the time and effort that I had put into the little terd made me very attached to him and him to me. As I'm typing this he's stuck in a bit of a time out ever since moving he has gotten very aggressive towards my husband, to the point where he sometimes goes out of his way to bite him...and not in a nice way. Now I had to deal with the bad biting when I first started to deal with Chewpa and I know how much it hurts. I'm just not sure how to go about making Chewpa stop biting the husband, I understand he is most likely being possessive of me and see's my husband as a threat but he didnt use to be that way. If anyone has some pointers on how to deal with this sort of bad behavior I welcome any advice. ^_^ I promise to post some pics of my little man soon.
Cheers

Believe it or not he was named after my husbands character from a mmo that we play together lol.

Have your hubby do some target training with the lil bugger. My green cheek still has moments of being aggressive with her "don't touch me or ill bite you neck lunge attack" I will give her a time out and then in a few minutes take her out and do step ups and target training. It shows her my hands are not a threat and good treats come to good birdies What mmo ?
