Hello, so recently i bought a new male lovebird to accompany my female one while iam away, but everytime my female lovebird sees him, she lunches towards him to bite his neck, for now they are separated into two cages and put the cages near each other, note that i bought the male one just today, so they saw each other for half a day now, she is not aggressive towards me or anything, only towards other birds, any advice?
