What makes a big shadow so blurry?

I've had to make some assumptions about what you're really asking here; if I'm wrong, please clarify your question and ask again.

A "big" shadow usually happens when the object casting the shadow is a long way from the surface it's casting the shadow on.

Light refracts and spreads, and the more distance it has to do this in, the more it refracts and spreads.

The combination of the two factors means that a "big" shadow, where the surface is a long distance from the object casting the shadow, is likely to be more blurry than a "small" shadow where the object is near the surface.

How does a shadow change when the light source is moved?

Depends where the light source is located and how many. Light will diffract around objects, so depending on the size of the object and the distance the light source is from it, more than one shadow can be cast, or at least it can have larger or smaller blurry edges which change when the light source is moved.
