Perhaps this has been answered elsewhere, but.... I have a 1 year old rooster who has been the only roo his whole life with 17 hens. He is an absolute doll, very very friendly both to me and his hens. I am adding 12 new hens this year and would like to add 2 or 3 more roosters for yard patrol and protection (I free-range). Will adding new roosters change the personality of my current one (ie make him more aggresive)?
