Can someone tell me what this is?

So they behaved in the avairy just as they would in nature if there was no other birds near by.
People do get so hung up about this, when as long as the situation is remedied. As you have done. It is just the way bird life behaves.
The egyptian royal families also did this for years - but that's another story.

Ok thanks, but I do want to see what you are calling yellows.
You can get split Australian yellow but you can't get split Euro yellows only single factor hens and cock birds. The single factor hens have a yellow back and cocks have a wishy-washy greenish yellow back.
