No location effect was observed when feather quality was evaluated (Table 4). The main effect of flooring type influenced the proportion of ducks with 0 or 1 scores (P ≤ 0.05). Ducks reared on litter had a higher proportion of 0 scores compared with ducks on slats at all ages. A greater proportion of 32-d-old ducks had a score of 2 compared with 7-d-old ducks, resulting in an age main effect (P < 0.01, Table 5).
