The last time I tried to 'make' my Amazon do anything, it did not turn out well. Whether a larger parrot or a small parrot, they are not puppets that we have full control over. Even when our parrots are well socialized, things can and do happen. It is important to understand that whether we are taking about children (and some adults) or parrots, there will be those that get along and those that just cannot. And, even when they appear to get along, well, everyone has a bad day. When both parrots are the same and have been friendly with each other, that bad day thing can still occur.
To a degree, having more than one parrot becomes a process of a third party trying to prevent a war. With great luck, some go along fairly easily and others it is an on going intervention. When you bring to this mix parties of greatly different size and therefore capabilities, when a bad day occurs, it can be very serious maybe even deadly to the smaller party.
So, you are responsible for maintaining separate areas and when there is a gathering, you are the one that must at all times manage (minimize) bad behavior. Remember, that there is nothing in Nature that would place these two parrots in the same place and time and assure harmony.
Good luck on your new role of peace keeper!
