I have recently run into a problem with my IRN and her cage - she is in a double cage which is divided and on the other side is my African Brown Headed parrot. My IRN is growing up and starting to mature and even becoming a brat at times. Her and my parrot got along fine until recently where my IRN started nipping at her through the cage.
I have decided that they NEED to be moved - this just isn't safe. It has only been going on for a few days and was hoping it would stop, but I don't want anyone to get hurt.
I have a single cage which my Cockatiels are in and was going to move the Cockatiels into the double cage as they were all together at one time and fine and move my IRN into the other cage.
I do have a question though on weather it is big enough for her. It is inches wide - 22 inches in depth and 36 inches inside height. They have all been switched for the day to see how everyone will do and my IRN seems very happy and playing with all the toys moving around and she does not seem or looked cramped at all.
Here is a picture of the cage - it is not my cage, but a replica of the cage I have.

Is this cage big enough for her?
