Speaking of geese, I have heard that geese will deter birds of prey. I have not yet seen evidence of this myself, my geese are still to young to defend anyone, but it might be something to look into.I have spoken to the owners, I've made them aware of this. They told me they needed to buy her falconer gloves so she did not injure herself on their property. So, lo and behold... she now has gloves!
They do not seem to mind her doing this, of course they don't have chickens - instead they just have geese and horses...
