Well, I'll just post my 2 cents worth.......we just killed two fox that were coming onto our property trying their best to get to my chickens! I really hate to have to kill any animal, but in this case we had shot numerous shots to try and scare them off and tried to throw things at them and everything. It was as though they were laughing at us.....they would walk or trot a few feet away and then turn around and look at us. They were not scared of anything that we did!!!!
I've had a whole flock wiped out by two stray dogs in the past....before I put up a six foot no climb fence and built coops that were covered completely with broadcloth wire and plywood 2 feet up from the base. We also put truck pallets on the floor inside the coop and put sheets of plywood on top of that.....so nothing could get in from any angle. I haven't had any problem with wild animals getting into my coop at night, but I do worry about them during the day when they free range...even if the ARE BEHIND THE 6 foot fence!
These fox were going to be a problem and I had tried to chase them away. I know a lot of people try to catch them in live traps, but I always worry that even though you take them somewhere else....you are just taking the problem to someone else. So, we shot them both with a shotgun. End of story! I love my chickens more than I love a wild fox that can kill my chickens or worse carry rabies and attack my family or my pets....so they had to go.
Also, if you call Wildlife and Fisheries or any of the Animal Control facilities, Police, etc. They can't help you....so you have to take care of business yourself. Like I said before....I don't like killing any animal...but sometimes it's necessary for you to make the choice.
