Egg laying performance of guinea hens reared on two production systems, floor and cage, was evaluated using 60 guinea pullets for either production systems. The birds were randomly selected from an existing guinea fowl population reared at the Teaching and Research Farm. Parameters monitored were age at sexual maturity, body weight at first egg, egg number, egg weight and egg mass till 72 weeks of age. Birds reared under both production systems had access to ad libitum feed and water and were under similar routine practices. Data collected from both groups were compared using the unpaired t-test. The result indicated that production system had no significant effect (P>0.05) on age at first egg, body weight at first egg, total feed intake to first egg, egg weight and number of eggs laid. However, birds kept in cages came into lay 21 days before those kept on the deep litter and had slightly lower body weight at first egg. Results obtained revealed that though birds raised in cages had lower feed intake, better feed efficiency and attained sexual maturity earlier, they laid 8.59 eggs less (P>0.05) than birds on the litter.
