Hi there, I am a new member so bare with me! I have a 19 month old black headed caique who has recently got really aggressive for no reason and given me a nasty bite. Usually however he is cute and cuddly.since then he has tried to do the same but I have escaped his attempts. Is is right for me to think of getting him a friend and if so should it be the opposite sex or does it matter ? Oh by the was he ( well I think it's a he! ) has been a little frisky on my hand, if you know what I mean !!
