I had problems during the day too, foxes and coyotes would race out of the woods, grab a chicken and run away with it. One day some of my egg customers saw it happen! Because I do want to free range, husband and I put up a 4 foot fence to surround the free range area. Now it's not possible for an animal to "run in" grab and run out. I haven't lost any more chickens to daytime predators. The run is a 50'x50' area and (so far) the chickens are satisfied with the space and even though they can, they haven't jumped the fence! My coop and run are predator proof and the flock is safe during the night! A simple fence worked for me, give that a try. Good Luck!
