My coop is about 50 feet away from my house. Late at night when I let my dog (a black lab) out to potty, lately she runs over there and barks hardcore and runs around the coop. She is very familiar with the chickens, and this behavior just started, so I am positive she's not barking at the chickens! How can I find out what is lurking back there? The coop is in the corner of our fenced in yard, there are trees around it and a flood channel behind our house. I'm sure we have various predators milling around the area, but is there any way to find out what specifically she is barking at? Our neighbor has a jack russel and has also been barking lately on their side of the fence around the same area. I live in a neighborhood in north Austin, Texas. Any ideas? Should I just set up various traps or what? I know my coop is secure but it still bothers me and I know it must be bothering my chickens that something is lurking around them! Thanks!
