When our first family was still intact, Max and Calypso got along. They certainly weren't friendly, but they never attacked each other. Now that we're a smaller flock, that's changed.
Max has developed an animosity toward Calypso, as evidenced here:
As a single lady, this has become quite the challenge. Max hates the caiques. The caiques hate each other. I am only one person! It is very challenging to have them out at the same time.
I plan to buy a house in the next few months, and I'm hoping them to design a space that works for my parrots.
