As Im new to the forum I dont want to upset anyone sorry if this does, but I thought I would share my views too.
I have found to this thread both informative and quite disturbing.
I for one would defornately not feed foxes and am one for a control of foxes ie humane traps or suitable gun( shot gun, 303 rifle).
My neighbours and I all have very adequate fencing for are birds, and have the agreement that if we have more then 1 fox running are properties they have to be shot leving just the 1. I feel we can be no fairer than that.
With response to an earlier reply its are responsiblity to secure are animals it quite right, you wouldnt put cows in a field with no fences or hedges to roam the roads and so forth, but whilst writting this I have just received a phone call from a very dear friend 5 mins drive away very upset

that 38 of her 40 hens 7 of her 4 ducks have been killed and only 1 hen was taken by a fox today

, this is someone who has spent nearly £6000 pounds putting 8ft tall fencing dug into ground with 2 electric strand wires all the way round her paddocks, so I will be going out with the guns tonight and a big thumbs up to all you who cull to protect, and
a big thumbs down to those who humanely catch and then release 30 miles away for someone else to suffer the cruel horrible wrath of this pretty wild animal.sorry to ramble
Sorry for your friends loss of birds, it must have been horrible for them.
Regarding relocating foxes I think it is mainly some pest control operatives in urban areas that do this (nice little earner where I used to live!) when trapping foxes for people who don't want them in their location but can't stand the thought of them being killed and therefore ask for them to be 'set free' somewhere 'in the country' where they belong!!! This is also, of course, cruel as the fox will then be in the territory of another and will probably not be able to survive long anyway. Much better to have shot it in the first place.
