I agree with previous posters that say three is too many for the number of hens you have.. and that agressive roosters should not be tolerated. I am fortunate that I have not had to rehome or process a rooster due to behavior.. but would not hesitate. Being an unreformed hatchaholic.. there will be another roo to replace the mean one in no time.. I can't tolerate mean animals.. especially when I am feeding them!
