Next time a fox gets into a chicken coop persuade the owner to keep his distance after the fox has done his killing and see what the fox does. I’ll bet a years wages he comes back and takes the other dead chickens. The only species kills for pleasure or fun is man. If the fox was that destructive how do we manage to have free range chickens in the shops ?
Any animal disturbed after his kill will abandon it if it isn’t strong enough to defend it.
It’s not nice for the chicken owners but the fox is simply doing what comes naturally, i’ll also wager another years salary that dogs kill far more livestock than foxes ever will, they certainly kill and maim more children.
