I have a question about my spangles.I have bred a DF spangle (yellow) to a SF spangle opaline greywing cobalt (hen) they only had one egg hatch & the resulting baby has very interesting colouring.The chick has yellow head,mantle & wings that also goes halfway down the body.Spangle wing markings with white flight feathers.The back,underbelly,vent & around the legs has come through a blue/purple/grey colour & on base near tail has slight green then yellow tail feathers.I will get a pic soon as I can get hold of a camera! Can the father (DF spangle) be hiding other mutations?
The double factor spangle could be masking any other mutation and either bird could be split for other mutations. It sounds like your chick is a single factor spangle with another mutation as well. From your description I would guess yellow face recessive pied spangle
