Golden Campines cannot be split to silver. Only silver roosters can be (possibly) split. The gene responsible for color for the Campines is designated with an "S" for "silver" and an "s" for "not silver" (aka "gold" aka wild type.). The silver gene is incompletely dominant. In addition, females only carry one gene for color, either from her father or mother. In other words, if she looks silver, she is (S/-) genetically pure for silver. If she is gold, she is (s/-) genetically pure for "not silver." Therefore, if the bird is S/s it will look silver. The only way to have a gold male is for him to be s/s and genetically pure for gold. .
