Foxes are a problem here too. I saw one last night, well before dark, sitting in the trees next to my field. My hens had gone in their sheds, but Mr Fox was probably hanging around thinking he may nip in and take one. They do not always take the lot, a fox comes in our field during the day, and sometimes helps itself to just one, to carry off.
They do have cubs to feed, but there are plenty of rabbits, and should be able to catch enough young ones rather than our hens. I have no problem with shooting foxes, or live traps, but have to agree with the man who comes shooting on our land ....and that is, he will not shoot at this time of year while they have young in the nest. Much as foxes cause me sorrow and pain, my love of wildlife and nature would not allow me to murder their mum and leave them starving ...daft I know!!
