The bird in the little pic looks almost like a blue buff columbian. The bird looks a generation or two on from a buff cross blue.
From the birds in the pics, you could try using your sort of gold splash columbian type male, he looks to be heading in the direction of a splash version of the bird in the little pic. You could try him on the female with the gold on her breast. It is not possible to tell what the solid colour birds might carry. Perhaps the above mentioned male on all of the related females & see what happens?
