Will a fresh, unprogrammed chip oscillate if it is powered up?

I have a circuit with ICSP that seems to have two problems - first I can't
get my programmer to successfully program it, and second, I don't find any
signal on the oscillator pins.

The first problem is probably going to fall after I make a shorter
programmer cable, and double check all the connections, and remove some
capacitance that might be in the MCLR line. This has deviled me before. I'll
make sure the chip really has 5V and also double check all the wiring to the
PIC.

Meanwhile, though, I expected the chip would oscillate by default, and I am
wondering if I should be seeing something on the OSC pins or not.  I am
using a 4 MHz crystal, which should require the XT oscillator option.  What
is the default oscillator fuse on a 16F73?
