sadly, relocating her would probably be a death sentence. she at least knows where to shelter and hunt where she is now. if you relocate her, she's at a definite disadvantage both in avoiding predators and finding food. best solution would be to find her an adoptive family, but that doesn't sound like it would be possible given the timing.
but imo, leaving her where she is at her young age, although dangerous, is the best course of action. not sure what type of humane societies there are in greece or if the owner would allow her to be surrendered...
