first of all how long have you had them home...did you get both at once is next question and did you bother at all to quarantine them each for a period of min...6weeks?? Which you should do...

then next question is how big is the cage??

then..this...you shouldnt even begin to think about doing any training of any sort and not even put your hand in the cage for at least 10days to let them both get use to their new surrounding ...activities ...you...and you absolutely should not attempt to grab and hold them as they are not like other parrots they hate being held or petted...

if you dont have the other bird trained and you have them both together before even having a chance to get to know one another from DIFFERENT CAGES for quarantine purposes also...its not likely this will be a easy job of training at all cuz you dont even have one trained.
