I have a question: Should I be concerned about fighting when adding 10 japanese BTW 8 month old hens to my 5 month old japanese BTW rooster? I am assuming he will realize they are girls and not other roosters? (all the girls are coming from the same place) Should I add all of the hens at once? Or a few at the time? **I have another BTW rooster, I actually have 2 (see my avatar). I have decided to just add my non-dominant rooster, Luther, to the hens and leave the dominant one, Tiger, out to free range. I'm sure Tiger will spend the majority of his day going up and down the fence line, but I just don't have any other choice at the moment. If I can find a really good home for him, I can let him go with a few of the hens. BUt, until then, he'll be free-ranging!
