I was wondering if anyone could tell me the type of colour mutation my budgie Charlie has?
He's got a yellow face and he seems like he has bluey/greeny patches on his front.
He's 3-4 months old and I think he's moulting at the moment.
If he is a sf Yellowface Type II, then he will continue to develop greenish feathers on his chest and belly, so expect him to change color after his first molt! If he mainly keeps the blue feathers after the molt then he is a df Yellowface Type II.
