I need help I have had coyotes coming up onto my property at night and I need them to go away!!?

I live in the country on 3.5 acres in North Central Oklahoma, I have 6 dogs, many cats and chickens. The chickens are in a pen up front near the house, I did this specifically to protect against predators. We really have been lucky we haven't had problems with predators for the past 5 years, until now. Since the temperature has started dropping at night, we have had a problem with coyotes coming right up to our back and side fence in the back yard and last night they actually came into the front really close to the house. One of my dogs is a Husky/ Wolf hybrid and he urinates all over the property so I can tell you wolf urine does not deter the coyotes one of my other dogs is a Great Pyrenees /Anatolian Shepard mix and he does an awesome job keeping the coyotes from actually coming into the back yard. However the coyotes just keep coming in night after night, for the past month my cats get brought in just before dusk to prevent them from being picked off but I need ideas to make the coyotes go away, so that our lives can return to normal. Please Help!
