thank you, they do love each other as they were bought as babies together although from a different breeder, one is black head caique and the other green tighed caique.
but sometimes they squabble and i hate it when they do this. i usually get the black headed one out and let her fly around or sit with us and then i let the other one out, that seem to stop them, some time they scream really loud that i have to cover them up for a little while that stops them. but mostly they get on great, they always sleep together in the hammock, its so sweet they lie down on thier side cuddled up. so i would never separate them at night, just maybe when i am at work.
