Yep I agree. For the very short term cup your hands and warm it gently like that.
Ideally for the medium term you need some kind of box with a 100watt light bulb, some chick crumbs and water (in a dish with stones to stop it falling in and drowning). Ideal temperature is around 95f for the first couple of weeks so a thermometer would also be great.
Hope this helps! Good luck and let us know how it goes!
