As @Ridgerunner mentioned earlier, a barred hen cannot produce a solid son as she has only one locus for the barring gene and therefore passes that gene, be it barred or non-barred, onto her son without exception. It is in this manner that black sex linkage works, as she is unable to pass the gene to her daughters.
His father was likely dark-barred, possessing only one barring gene; he is therefore able to produce both barred and solid offspring according to which of his two genes they inherit.
