I got two new budgies but I wasn't totally sure about the mutations. I think she may be sky blue sf dominant pied but she has a lot of white maybe recessive but the bottom half of her wings are white. I'm pretty sure she is pied though
I'm not an expert on mutations, but she's cute, cute, cute! Are you sure she's not a male? Perhaps the photos aren't portraying what the cere looks like in real life, but she looks like a he in the 2nd and 3rd photos.
I think you're mostly right! I am taking your word for Skyblue as photos can look lighter or darker, but I agree with sf Dominant Pied and would add Opaline too. See the reduced barring over her head and shoulders, and the blue body colour over her shoulders/mantle and in the wing markings? Thats Opaline.
