I have frost free Hose bibs but they can still be frozen and broken if the hose has water left in it. you can get a thing called a "vacuum breaker" that lets the hose drain out if its lower the bib. if the hose is left with pressure in it it won't drain and will freeze.
Myself I use a large Y fitting with shut offs on it to bleed the hose. when I shut the water off on the house outside I open the Y and let the water drain out of the un-rolled hose ( it runs slightly down hill away from the house) if I get it just right the hose never freezes. it runs right to the front of the Goose pen gate and pools out.
