It takes time for a bird that falls in love with their mate to accept boyfriends - girlfriends. My conures haven't done that I guess because there are two of them together. Plus, they only have had one home. Diana is right with her advice and it does take a bunch of time and patience. They are like kids. They try to get attention and do all sorts of bad things, they want attention even if it is bad attention. The other birds may join in for a while simply because they all feel they need to be the loudest.
