im having a similar problem, i have a couple sets of two year old male red goldens , one with 3 hens one with 2 , must have had 40 eggs so far , none were fertile, real bummer. not like there not prancing around a lot showing off to the girls, 
but its not just the reds , also have a couple sets of silvers , but there only spotty laying , all infertile. a trieo of aldy amhurst , just started to lay , no fertile eggs there , but he is just starting to color a bit . the ringnecks  layed during the winter , had a real low hatch rate, not laying now.
turkey hatch rate is improving as well as the chickens and in getting over run with Japanese quail 
got to find a set of hens for my yellow boys this year .
