Added a new budgie to the flock - any advice on behaviour?
The blue-white clearwing (male) and lutino (female) have been together for half a year, and I got them a buddy (the rainbow one, male, 10 weeks old). He's just completed quarantine and I put his cage into the bird room, then opened both cages so they could interact outside on a toy I have. Vain effort - in less than a minute the rainbow was inside the other two's cage. I added his seeds to the food bowls, in which were just pellets before, and the two adults are munching them up happily. I'm a bit worried about the rainbow's behaviour in the video however. He flies into others, and the lutino doesn't seem to like him particularly. Is this kind of behaviour normal for the first day? The cage is open and any of them could go to the quarantine cage if they'd get fed up with each other.
Since making the video I've moved a food bowl closer to the other two since it has been ignored up to now. No clue if that changed anything yet, but I've seen the rainbow eat when the clearwing went to preen.
