Went out to walk dog and saw a cluster of colored lights moving irradically (zig-zaging) and then noticed additional similar clusters.

The object was too far away to determine it's shape but had multiple red, green and blue lights flashing and the craft moved in a very irradic fashion. Sometimes still and then quickly moving in a zig-zag fashion unlike the movement of a normal aircraft or helicopter. We observed additional similar light groups that were spaced out and further away from us. It is now almost 1 am and we still see them, the closest one having moved a considerable distance from where we first observed it.
