My cockatiel kiwi is a female living with eli who is also a female in a comfortable cage. They were friends until one day kiwi started to chase eli and didnt stop until they were out of breath and that continued for days. I have no idea whats the problem with kiwi. They have the toys to play with, she wasnt intoxicated by any sprays from what i know and im just worried that Eli will get killed. Please help!
