Answer: If the tree looks otherwise healthy; if it is the right color and you see new growth each spring, I suspect a creature is nibbling on your trees. Do you have deer in the area? How about raccoons or squirrels. I suspect a large 4 legged animal is munching on your trees. You can try applying a spray on deterrent such as Deer Away to the tips of the branches to thwart further feeding. Aside from a deterrent, or going to the expense of fencing the entire area, I can't think of another solution to the problem. Wish I had better news for you!
