Awww love baby chicks. Yes I am also breeding to improve the RB line and will only be breeding the darkest and easiest to auto-sex at hatch. Hopefully I will have my first backcross early fall. That backcross to RB will have 1 generation of HRIR breeding before backcrossing. I will also be doing another generation backcross to HRIR before crossing back to my RB.
