Sunny is not too young to tell his gender and appears a bit older than 6 weeks.
He is a very handsome little male.
The deep translucent pinkish-purple cere tells you he's male.
As an FYI, budgies should not be released from breeders until they are a minimum of 8 weeks old to ensure they are fully fledged and weaned and minimize the chance of regression.

Little update and wondering if he's 'still' a boy. Lol
By the way he does have natural perches now and a new bigger cage with lots of foraging toys.
Is it normal for his cere to start turning blue already? I have a couple of pictures but the different light makes it look different every time I look at him, I have one pic where its bright blue but more purple/blue in real life. We have just got him a friend and I'm praying he is a boy too. Thanks!
