This study was to investigate the laying behavior of Brown Tsaiya ducks. The effects of color, structure, pad materials, and covertness of nest on the choice of laying place were explored. Laying position was not affected by the color of nest. The ducks preferred to lay eggs in the nest that located close to the wall. The pad materials in nest had a significant effect on the selection of laying position. Ducks laid more eggs in the nest with rice hull, followed by rice straw and artificial turf. Although a great variation was observed among replicates, however, the soft-pad nest in the covert area attracted more ducks to lay.
