I have taken in a polish rooster that has been bullied at his previous home. I have him in a hutch alone but in sight of ducks and chickens. I am not sure when I should introduce him to the other roosters and hens. My other roosters and hens are only about 4 months old and I am not sure the age of this polish fella. I also have a flock of 1 and a half month old chickens that I have thought of introducing him to. I am trying to figure out the best way to do this without any blood shed. Any ideas?
