I'm still a fledgling compared to other breeders on this site, and as such, I could really do with some help!

Our aviary seems good. A nice approximate size of 6.5m by 7m and a height of about 4m. We inserted stumps and planted some savanna-like grass stems which are wonderfully green during the summer, and slightly dry in the winter. The earth is covered with red sand and we've placed several types of enclosed nests in the upper corners, and in the tree. It has a very flat drinking hole, which is easy to get out of, deep enough for bathing, with a pipe that allows us to drain the water out of the cage when cleaned. Three mystic sprinklers are placed within the cage and turned on for half an hour during the evening when it's not too cold. And since the cage is on our farm in the savanna, the workers often collect heaps of dried twigs and grass for me to put inside. I also occasionally put in the soft belly feathers of the guiney fowls we hunt once in a blue moon and more often place little chunks of cotton in there. It's usually gone after a mere hour or two.

It contains a pair of each of the following so far

Chestnut Flanked Zebra Finch
Society Finch
Red Cheeked Cordon Blue
Gouldian Finch
Diamon Dove
Bourke Parakeet
Chinese Quail
Singing Quail
Common Quail
Rabbits
Guiney Pigs
I personally want to get rid of the rabbits and Guiney pigs, but they're my sister's and the deal was that I could have the aviary if those were allowed in. They don't cause any trouble though, and live peacefully with the finches. I had some quarreling between the society and zebra a few days ago, for the zebra were the first to build their nest, and the society finches wanted to take it from them. So I hung another nest a meter or so away in the tree on the same height. I also places a little bit of grass and cotton in there. It worked. They raided the hanging home and left the zebras in peace.

My main problem now is a little gift I got from my mother. She bought me a pair of black throated parsons

Should I try to swop them at the pet shop for something else or is there any chance I can get them to blend in with the rest. I feel terrible about rejecting the gift, but she didn't know.
Thanks!
