Well the old hen, and pullet, should be silver based. It appears all her available silver males are split to gold.I am goping to test my learning here and ask...
Wouldn't it be best to test mate the 2 silvers (to each other) hatch a bunch of those eggs to be sure you are breeding silver to silver and THEN see what comes?
big medicine - correct me if I am way off as I am learning at your knee - so to speak
This breeding should produce
25 % silver laced pullets
25% gold laced pullets
25% silver laced cockerels
25% silver/gold split cockerels
