We got a new rooster today. Very beautiful, almost all black with very dark gray edges on his feathers. We introduced him to our flock, will he be fine w/o fighting? We've seen him scrimmage a little but he seems good.
Generally a rooster is one of the easiest adds to a flock. If he is younger than the girls, there may be a few dust ups, mine would not let the new boy sleep on the upper roost for 2 weeks, but all are in love now. Let them work it out on their terms!
