Well, for sure!!! Hy line brown is a commercial red sex-linked hybrid bred from this great company for laying having the excellent laying abilities it has, for being too small in size and for being color dex-linked.
The father lines must be red and having the golden gene. They must have be the excellent choice. So selecting them is a very hard job.
Excellent laying heritage breeds that have the golden gene are the rhode island red and the new hamshire. I don't know about the red leghorn. Maybe this breed too.
The mother line must be all white and have the silver gene. White leghorns don't have the silver gene. They are dominant white!!! Also they lay white eggs!!! But, I believe that the mother is hybrid bred from white leghorn and other layers who are excellent layers and have the silver gene.
