Thank you for replying. He is a lavender Orpington he will be a year old this spring. So will the hens, they are Isa Brown/sex links
Brown Sex Links are generally on the dominate end of things. They also bear confinement poorly and are often the first to pick on one another when bored... They are also often last to listen and submit to roosters (as I have experienced). Additionally, Orpingtons are not a superb flock protector breed... Orpington roosters tend to be mellow/docile instead of assertive. This makes them great as pets or in small, backyard flocks around kids. However, it means that they are not the best option as far as flock-keeping is concerned and are not very likely to keep hawks away... unless your hawks are intimidated by big, fluffy chickens.
Given the above factors, I would highly recommend getting a different breed of rooster and possibly considering providing more space for your chickens. Another option would be providing a covered run (like Aart brilliantly suggested).
Rhode Island Reds, Game breeds, Cubalayas and Malays are breeds that tend to be good protectors. However, many flock-protecting roosters display aggression towards people as well as predators (which I would be prepared for if you want to ensure a good flock protector. Here is a good article on the subject--->
All About Aggressive Roosters).
Jersey Giants are reputably good flock protectors (in spite of being generally docile and friendly towards people. You can read more reviews about them here-->
Jersey Giant Reviews). My Welsummer was a very good flock protector and died defending his hens but was very friendly and sweet towards people. However, not all Welsummers have the same temperament.
