Before I noticed the chip all was well, no one was at the top and no one at the bottom, because there's only two. They were just two best buds. Now the slightly older (about a week older) one has a chip in her beak, the younger ones been picking on her, trying to stand on her, nipping at her tail when she thinks I'm not looking. She tries to fight it by standing up for herself but she gets to excited and bumps the other ones chest and I have to break it up.
Silly girls
Here the both are, if click for the larger photo you can see the chip
