That is how it done.

Blue Buff Coumbian genetic make up: eb/eb, Co/Co, s+/s+, Bl/bl+.
Golden Partridge genetic make up: eb/eb, co+/co+, s+/-, bl+/bl+

the result will be 50% of Pullets: eb/eb, Co/co+, s+/-, Bl/bl+, they will look like blue buff columbian. if these pullets are cross back to golden partridge your chances of getting blue partridge is only 25%(both genders, so 12.5% if you only need females), because the other will be regular partridge(25%), Buff Columbian(25%) and Blue Buff Columbian(25%)

I’m loving her coloring.
I hatched another pullet with the same coloring so now I have 2 of these beauties.
