No voice changes here the MicroHen Duck Call by Rich-N-Tone is deliberately undersized in order to produce the squeaky, raspy, high-pitched sounds of a young hen. A softer wood that allows for the production of softer, deeper, mellower sounds than more dense woods, Bocote is noted for its tannish yellow color with dramatic dark brown to almost black striping. A perfect complement to other Rich-N-Tone duck calls due to its different sound, this call is also ideal for late season calling, timber, or imitating young mallard hens. Available: Bocote Wood.
