We present measurements of the branching fraction and time-dependent CP-violating asymmetries in B{sup 0}{yields}K{sub S}{sup 0}K{sub S}{sup 0}K{sub S}{sup 0} decays based on 227x10{sup 6} {upsilon}(4S){yields}BB decays collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. We obtain a branching fraction of (6.9{sub -0.8}{sup +0.9}{+-}0.6)x10{sup -6}, and CP asymmetries C=-0.34{sub -0.25}{sup +0.28}{+-}0.05 and S=-0.71{sub -0.32}{sup +0.38}{+-}0.04, where the first uncertainties are statistical and the second systematic.
