UPDATE on The Odd Couple

Bully-boy (the Cockatiel) & Candy (the Parakeet)

The Odd Couple are no longer for sale as a pair.
We purchased another parakeet (a white albino Rosemary named Fluffy) for Candy and gave Bully-boy a mate from our stock of Cockatiels.

Bully-boy is fine with females.
Both pairs have their own honey-moon suites.
(Their own cages.)

Since then we found a buyer for Bully-boy and his potential mate.
This man knew enough about Cockatiels that I am confident he will have no problems or very few with Bully-Boy.

My wife, Rosemary wants to keep the parakeets.
If we had sold this odd couple, we would have purchased 2 new parakeets with the money.
Now we have a pair and Rosemary is talking about acquiring more parakeets in the future. Parakeets talk less clear but they do take up less space since you can fit more in one decent size cage.
