lovely birds lindsey, but they are not the exact same varieties... you have a spangle and a spangle opaline by the looks.
I know I thought the same thing myself! But through breeding they are indeed both just spangles not opaline spangles They are split to opaline though
When they were young they had black spangle markings just like any other spangle with no coloring, but with moulting they have changed to the colors they have now
I posted pictures on here of them too and barrie and nev said they had spangles looking exactly like them but were not opalines.
Zest( I am assuming you mean him as the spangle opaline) has had 2 clutches with an opaline female with the outcomes being 9 chicks, and of them 3 opaline females, 1 normal female, 1 opaline male, and 4 normal males
Heres some pics of the babies... And Avacado has had the same outcomes when paired to another opaline hen. Go figure!
