In this study, the effect of nest box curtain color on the complex behavior of nest box choice of brown and white layer hens bred in a free-range system, an alternative breeding system to battery cages, was analyzed. Yellow, blue, red, and green curtains were placed randomly in the entrance of the nest boxes, and the color of the nest box curtain was observed to affect the egg-laying choices of the hens (P<0.01), while the curtain color x genotype interaction was determined to bear no significance. According to the results, the nest box choices of white layer hens were 36.53%, 17.54%, 15.42%, and 23.64% for red, blue, green, and yellow, respectively; these percentages were 35.01%, 17.52%, 17.66%, and 23.43% for the brown layer hens in the respective order of the colors. On the other hand, the percentage of eggs laid on the ground was determined to be significantly lower in both white and brown layer hens, compared to the control group (P<0.01).
