Bird bullying
So i have 2 cockatiels. It is a male and a female. Female has dots and stripes under her wings so i am sure about her gender. So i had my male before i got the female and now she is bullying my male because the male’s smaller than her. She also acts like a male by singing and dancing infront of him. And now she doesn’t allow the male to do anything what he wants. She fights with him. And i dont have another cage to separate them. Can u tell me what to do? Its like they are both males.
