Hi there.
I have a four year old male, rainbow lorikeet named Bronson. Originally, I had him and a black capped conure who unfortunately passed away 3 months ago from genetic problems. They got along well enough (they were in seperate cages but played together often) and both of their temperaments were great.

Last month, I adopted a pied rainbow lorikeet who I named Bailey, so Bronson wouldn't get so lonely. Bailey isn't DNA sexed. They are housed seperately but are allowed out to play with eachother often. Recently Bronson has started to become very aggressive with me. They both have day cages outside in the yard and night cages inside where they sleep. Every time I'm bringing Bronson in to his night cage and taking him out in the morning, he's biting me very hard and latching on. I expected a behavioural change once I got Bailey but I didn't expect Bronson to turn this way. What am I doing/have I done wrong? What can I do to stop him being so aggressive towards me now.

Thank you for any advice!!
Laura
