Meteor Showers and Their Parent Comets
They showed that ejection could have occurred as recently as 1500 years ago.8
They also found that the Quadrantid meteoroids might be moving in chaotic orbits
, a phenomenon associated with overlapping mean-motion resonances.

Icy Bodies of the Solar System (IAU S263)
We have modeled the observed light curves and decelerations of Geminid and
Quadrantid meteors and studied their spectra. In both cases, we have found
typical bulk densities of about 2600 kg m-3, much larger than in cometary
meteoroids.

The Quadrantid stream is much younger and is affected by strong Jovian
perturbations giving rise to irregular changes in its activity. The Poynting-
Robertson effect appears to deplete the smaller meteoroids from a stream so that
old streams ...

the Quadrantid stream is about 16 thousand years. At the same conference!
