A short term dietary self-selection experiment (28 days) was conducted with laying hens fed three treatments (T1-T3) consisting of a commercially available layer feed (Tl, single choice), commercially available layer feed and oyster shell grit offered separately (T2, two choices) and a corn mixture, soyabean meal mixture and oyster shell gut offered separately (T3, three choices). Measurement of feed intake was divided into three feeding periods, from 0800-1'2(X)h, 1200-16Q0h and 160(W800h. Feed and xvater were available zA libitum. Hens were raised under 15 hour photoperiod. Feed, energy and protein intakes were significantly greater on the commercial diet and lower in the other two treatments. Calcium intake was significantly lower on the single choice and threechoice diets. In all treatments, the hens tended to consume more feed during the period between 1600-0800h (40.8-45,8% feed consumed), that is very late in the evening and very early in the morning. Similar amounts of feed (26.2-29.7% of feed consumed) were consumed between 0800-1200h and 1200-1600h. Egg production, egg mass and feed conversion were significantly better on the two and three-choice diets as compared to the single diet. There was no difference in egg weight among the three treatments.
