Thank you for your help. I believe the damage is done and I may have to get rid of a few roosters. I was trying to make it more peaceful and only caused aggression and messed up the total balance for the flock. Lesson learned.
I put collars on two bantams and an americana trying to guilt the crowing. Now the most mild of all three attacked the most agresive and did a lot of damage. The whole flock is in an tissy. How do I calm everyone down.
