Over the years living where there been lions bears wolves coyotes bobcats coatamunges badgers racoons weasels ferrits. I noticed when i got rid of one bad actor a worse one always moved in . For a while you may have to educate the predetors that you already have, untill coyotes move in. Instead of trying to kill the predators you have now , ruin there fun instead make sure they know your their trying to make a meal out of them ! Mark your territory just like a coyote would do .use a bottle to pee in ,use it to mark your territory .each day before night fall same places . When you shoot you want to make them sting good so they teach others , your always there ! use a shot gun with bird shot . Dont aim to kill aim to sting their butts. Make sure they know its you to be afraid of.. mark your territory with that pee bottle ,after a while you wont have to mark so much it will stink to them bad in each spot you daily mark they have you on their minds because of it.. Hopefully you will hear coyotes some day that will take over your job.untill coyotes move in use your Pee bottle to keep the prediators away from where your birds roost and feed to!
