I haven't read all replies, so apologies if this is repetitive.
1. stop coyotes from digging under fencing by adding a skirt/apron
2. stop coyotes from easily scaling fencing by adding coyote roller bars
I'm sorry but once they have good hunting grounds they tend to come back until the food supply is depleted before moving on, day and night. Please take precautions to protect your dogs and cats as well.
Another thing that may help (though I usually see it for stopping bears) is making a scat mat. This might be a good addition near the actual coops where most birds will be at night.
