I had a family of foxes around my property for a while, I thought I was losing ducks to aerial predators (hawks are bad here too) until I picked up a young pup on one of my security cameras coming into my yard and stealing a chicken. I also realized my cats were sticking closer to home, and...
Such keen senses they have.
I got a pic of a coyote on my game cam, directly in front of my chicken coop, where I had burned a few feed bags. He sniffed the burnt stuff and moved on. (this time)
