My family and I have had a red fox hanging around. Three years ago we attempted to shoot it but missed, so we decided it was okay that if it could coexist with us in peace all would be cool. About four days ago it was walking very near our chickens. My ducks were freaking out. It was doing that weird face-plant into the snow (getting mice I’m assuming) but then turned it’s attention toward the birds. I’m very thankful that one of my sisters saw it and raised the alarm because I’m not sure what would have happened if we had not noticed it. We shot it, sadly. It was a male so I’m sure it had a mate nearby and maybe even babies so we are on the lookout just in case the female comes around.
Foxes are very very smart. It’s very difficult to trap them or poison them. The only solution I can think of is to shoot them. We were lucky because that fox hung around the entire five years we’ve had chickens and never bothered them—I felt terrible that it had to die but I felt like it was getting too close for comfort. Hopefully you don’t lose any more chickens!
