How do I tell my mother to stop trying to kill my birds?

serious question. I keep a few birds in my room so i can sell them (at alleyways, near drug stores, ebay whatever) but she says " RAH RAH RAH too many birds RAH RAH RAH I'm going to kill them" and she tries to kill them. I make a bit of money selling birds and I don't really want my birds dead. I only want my pet bird dead cause she's been a b**** after i took away her "male friend". so what should I do?
