I love your baby. I would lean towards boy with those pics though but I am no expert. I also do not know much about mutations but I wonder if the yellow on your male is making blue look green? My babies are starting to darken a bit and they look like mom but much closer. I would bet he will just darken a bit. So maybe sky blue?
Okay enough guessing someone with a clue will be along soon

Sakura is a normal cobalt with a violet factor. The colour and mutation has come from both parents. If this pair are not split for any other mutations they would be expected to produce all normal type chicks in the blue series and half of them will inherit yellow face. If Violet is double factor violet all the chicks would also inherit (single factor) violet but if she is single factor violet only half the chicks would inherit the violet
To get chicks the same as Barty, Violet would need to be split for recessive pied. To get opaline chicks like violet, Barty would have to be split for opaline
