I am looking for a rooster for my hens - 5 sex links and 2 silkies. I want him mainly to protect the ladies from daytime predators. Because of the two silkie hens, I am wondering if I need to get a bantam rooster and not a standard. I wouldn't want the girls injured by a large rooster. Will his size affect his ability to protect them (I mean I'm sure it will a bit, but is a bantam roo still an effective guardian)? Will the sexlinks take him seriously? I am starting to regret getting the silkies but I really want to keep them, so I hope to find a way to make this work. They are so cute!
