Hy-line Silver Brown breed

[D1939J]

Good afternoon,

I am from South Africa and raising a flock of Hy-line Silver Brown. Got them when when they were only 3 weeks old and today they are 14 weeks old. It is just from curiosity, I started to think, because they are a cross of indigenous chickens. What are their parents?
I need a light from you guys to help me understand the breed more.
I would appreciate any input who might be the parents of the breed.
Thank you in advance.

Hi, and welcome to the backyard!
Did a google search and found that hi-line is a international poultry supplier of some pretty teriffic sounding comercial layers.
It looks like your breed is a white legorn type, lays a medium to large egg. There was a link to download more information about the breed but download fails for me.
Sorry i am no help.
Happy you joined us, and Hello from Northern Michigan.

Welcome!

The hyline silver brown is not related to a white leghorn, that company does not like to reveal their birds to much
