Can Two Or More ATTinys Share One External Crystal?

Question

I've got two I2C Slave ATTiny85 chips both running at 16MHz with external crystals. Can they both share a single crystal with the 22pf caps? Is there anything wrong with this?

I don't have any free pins on the ATTinys to route a clock signal out of one ATTiny into another.

If there's some type of external clock circuit, how is that constructed and connected/shared with both ATTinys.
