Hi Demetria. If these two parrots have been raised together then placing them both in the same cage should not be too much of a problem. But if you take two parrots who have never seen each other and put them into the same cage, you maybe asking for trouble. Not all parrots like other parrots... just like humans.
The cage should be very large and it is nice to have the ones where they can sit on top of it and eat as well. If you read some of the posts in this section, we recently talked about cages and there is a link so that you can see the cage suggested.
