Im hoping to eventually breed my yellow fancy parakeet. I do not know weather this is a male or female bird as it can be harder to sex fancy, lutino and pied parakeets. I am a new bird owner. he/she has a lavender/purplish nose

There's really no way to ever know for sure, until one makes an egg. It's always a guessing game. Or you could go to a vet for the vet to make a very detailed examination of the bird ...

If you want to breed keets then that vet visit and discussion is your very first step! It's a serious undertaking.
