Since its a female, its highly possible that its a cuckoo hybrid judging from what i can see in the pics.
The hybrid is the result of breeding a solid color silkie to a cuckoo hen , the offspring can only be sex-links ..therfore your females will be solid color..however, ive seen hybrids have a few faint cuckoo markings or flecks that are unmistakably cuckoo..sometimes theyre molted out, sometimes theyre not.
Most people only want females, and if they dont know how those genetics work, they hatch birds that they think are not cuckoo..when they really are.
One sure way to know is keep her in a pen with a solid color rooster & mark the eggs that are hers..within a few days of hatching you will see about 50/50 solid color & cuckoo chicks...the barred ones will all be males.
Those hybrids are excellent to breed back to barred cuckoos, you get more disctint barring.
