Bird that carry white as the dominate color should not be used to cross for sex link hybrids they will not be sexable at hatch silver is the key ,,,
I'm not sure what you mean what Hendrix has done, ISAs have dominant white.

You are absolutely correct the leghorn is the key in the cross that gives them there exponetional output but the white color gene needs to be at a level not to interfear with the sex linking color gene if your parent stock is carrying the white gene as the dominant factor it will interfear with...

I am very interested in your riw cmom any pics of your parent stock ? You say they are good producers ? Close to that of a leghorn ? Strong silver genome ? Got me thinking ,,,, lol

That's great I have been working on a fourway , at the moment I am breeding my w leghorn to my silver wyandott hens trying to breed out the Dom white and add the silver gene to improve egg production but the Dom white seems to keep coming back instead of going the other way I want to boost the...
yea cmon they are a amazing hybrid , they set the standard that others are judged by I have done extensive reading on them and have visited ISA battery barns here in costa rica ISA does offer pullets for sale here with a 500 chick min the ISA was the primary reason for me to attemp my own sex...
