i have two cockatiels. a male and female ( from how they look) well the male one is always fighting with the female, for example, they have their own tree in my living room ( i don't keep them in a cage) and she will be on one side, and he will be on the other. he will go to her side while she is sleeping and bite her.
Is this normal? usually they get along unless one gets in the others "personal space". but they eat together and everything is fine...
I'm just worried because the other day i think he pulled out a feather by her mouth and she bleed every where (she is better now). how should i handle this or is this normal?
