TAZ part of what you are saying for me will be true As far as line breeding is concerned, but I have only kept a few pullets and one Roo from my original Sandhill flock. I will breed the pullets to a non related Roo. The ones I got from florida came out of different groups of breeding pens. I am breeding two big black pullets to the Mottled Roo and take out some of the white and introduce the mottled gene. Save the best and possibly breed back to Father depending on coloring and other type traits I am trying to achieve. I have a splash Roo I am breeding to blues and blacks unrelated to him. This will give me some new lines to work with. I am going to get another black roo from fl breeder. I can't wait till next year to see what I have then. I can mark eggs from different groups for selling.
