from the photos .Shiraz is a better looking and correct hen .
Queen =Dark eggs
Shiraz = Type and mass
work with them both with a cockerel to capture both traits .
Shiraz will help you better to breed for the Show if bred back to her grand son .you saying he is correct .you want to capture that is this line .
mate him to both and work with they progeny as half sibling /cousin line . the best cockerel from Queen X Son will cover the best pullets from Shiraz X grand son and verse versa . you end up with a pure inbred line with many great traits.
I have been doing a lot of study when I was in Europe last 4 months and I learn body type and mass are the first to be bred true . you can not breed any other trait properly if the bird has a wrong body type or lucking mass .
body type and body carriage plus mass they make up 70 point in a total of the score card .
chooks man
Yes that's why Queen and Sheraz are my two best girls, both good for different reasons but related and from the same line so they carry a lot of the same genetics. You reflect my plans exactly to line breed using them and the cockerel. Yes Sheraz is definitely better type wise, I agree. She is a big girl. Lol.
