Do you have a spare cage so you can quarantine?
Colours.....that's up to you

Do you have a breeder close to you? Check out the Trading Post to find one in your area. I'm so over pet shops! I saw a gorgeous blue spangle and I was ready to buy him but I took a good look at the other budgies in the cage and I walked out

One had poo stuck to his vent and there were undigested seeds in the poo! I don't know much, but I know that's not a good sign. If I do get more budgies (and I don't think I will any time soon) I'd get them from a breeder

They're cheaper and usually healthier too. That has been my experience anyway.
All the best Nicole! I hope you find your 2 new budgies

And keep your siblings away from them lol
