Yes I was a little bemused when I read and then researched this!
Apparently if you get a man to pee around the garden it deters the fox. Not a female, a full blooded male, apparently it fools the fox into thinking there is a bigger male around which makes him fearful for his life so he runs!
Perhaps this is the way forward with your poultry? I have discussed this with my husband and he said colourfully ‘absolutely not’.
So who is going to give this a go?
