I have had my two parakeets for 4 years. They have always lived together. One is a girl and one is a boy. Recently they started mating so I am thinking Oh good they love each other how sweet etc. well in the last 2 they started fighting and I mean really fighting. Rolling around on the bottom of the cage, clutched in each other claws and biting. Feathers flying everywhere. I literally have to pry them apart. Why would they just start fighting like that. I am afraid one of them is really going to get hurt. Anyone have parakeets or know why all of a sudden they would want to kill each other. They have always been fine together I am stumped.
