We discuss, in qualitative and quantitative fashion, the yields of hadron resonances. We show that these yields, in general, are not in chemical equilibrium. We evaluate the non-equilibrium abundances in a dynamic model implementing the 1 + 2 ↔ 3 resonance formation reactions. Due to the strength of these reactions, we show the Σ(1385) enhancement, and the Λ(1520) suppression explicitly.
