The suggestion of hadrons being "born" into equilibrium arose from long chemical equilibration times of hadrons in the hadron gas phase in relativistic heavy ion collisions. Here we consider possible Hagedorn states, which contribute to fast chemical equilibration times of baryon anti-baryon pairs (as well as kaon anti-kaon pairs) inside a hadron gas and just below the critical temperature. Master equations are used to describe the reactions. Within a Bjorken expansion scenario, the kaons and baryons as well as the bath of pions and Hagedorn resonances can indeed quickly chemically equilibrate.
