The gouldian is in it's own cage now, with a heat lamp. I have lots of cages, the issue is a suitable place to put them (I have cats, which limits my possibilities). I sacrificed a pair of budgies that had been separated for breeding (but hadn't started yet) and put them back in the main cage so the gouldian could have their cage.
I wouldn't say the pictures are showing the exact colors - the last two are taken with a flash and it does make the green color in particular more vibrant.
I really hope you are right about the red head - I'll have to admit I think those are the prettiest ^^
I'm not sure which breast color I like best, but to me it does look faintly purple even in its baby feathers. I don't know what white breast baby feathers look like though, so I'll just leave you to guessing at that
I'll just be looking forward to seeing what the little one will become.
