Hi everyone! I have two budgies Atari and Nova I always thought Nova (white) was a girl and Atari (blue) was a boy... But recently I've read some conflicting info, Atari (blue) is 9 months old and Nova (white) is 11 months old. Thanks for the help!
We are not Vets, Avian or otherwise. If you have any serious doubts about your budgies' health an appointment with an Avian vet should always be your first point of call.
