Conservation of baryon number as topological charge in effective chiral field theories imposes a local constraint on the time evolution of field configurations in the commonly used O(4) model. Possible consequences for the formation of chiral condensates after a quench from random initial configurations are discussed. It is argued that efficient dissipative terms are necessary but not sufficient to unwind the randomly curled-up initial configuration, before collective motion towards the condensate can grow. The existence of soliton stabilizing mechanisms will further prolong or prevent this process.
