Using a sample of 2.59×107 ψ(2S) decays collected by the CLEO-c detector, we present results of a study of χcJ (J=0, 1, 2) decays into baryon-antibaryon final states. We present the world's most precise measurements of the χcJ→pp̄ and χcJ→ΛΛ̄ branching fractions, and the first measurements of χc0 decays to other hyperons. These results illuminate the decay mechanism of the χc states.
