Fox killed all my chickens (but one)

[missyg4]

We try keeping a radio on a news channel or something with a lot of talking. It usually works, but fox tend to figure that out eventually too! Ammonia works for a while. We soaked small ropes with it (using a wick effect). But who wants to do that all over their property every couple of days. The best thing is to keep an outside dog that doesn't like to eat chickens.
