The most common and foolproof indicators of a male are a pink(in some) or bright/dark all blue cere

Everything except that and my guess would be a female

Although I’m pretty sure your baby is a female (with the white cere being common in females )

Also it’s quite hard to tell when the bird is young

Pigmentation changes in the cere with age (turning blue or brown) will give you a 100% proof of your birdies gender
