I nearly bought a Conure from a local pet shop, but it was 12 month old, you want them younger than that. Not to mention, they are too small and I wanted something bigger. Ringneck parakeets are about the perfect size. They aren't too big like a Macaw or a Cockatoo, while not too small like a Budgie, Cockatiel or Conure.
To be honest though, it's not always about size, I mean budgies are some of the most fun pets you can get.
Anyway, this is it:-
It just needs to settle now for a few days, then I can let it out a bit and enable it get used to its new(and much larger) environment
