I have a male silver Sebright I am breeding with gold females. I got 4 silver chicks from this which is exactly what I want. Not enough cause I think only one is a pullet. I want more chicks. Problem is A golden keeps getting into the the pen with my mating flock. Until I get the time to fix the breach in the pen; How long does a hen need to be away from the gold Rooster to be free of his chick batter?
