No, it means that there is a gene in there that will cause 25% chicks not to hatch. You can breed two lethal genes together, just expect that some chicks won't hatch. There are a few color genes in coturnix that has this. If you mix colors, it's hard to track it down but color surprises are nice.
ETA: in the golds, it's the Y (yellow gene) that causes lethality.
So does this mean that it would be best to breed golden hens to pharoah males or vice versa? So what would the results be from golden cross pharoahs? I keep both to gether now, so I don't really know what hatches from who. I know that my Silver Cots carry a similar gene.
