Duck body condition scoring. Ducks raised with water troughs showed significantly increased (and thus poorer quality) eye (A), feather cleanliness (C), and feather quality (D) scores compared to ducks raised with pin-metered water lines at ages 23 and 33 d. (B) Ducks raised with water troughs showed significantly higher nostril scores at age 9 d, but significantly lower nostril scores at age 33 d compared to ducks raised with pin-metered water lines. (E) Ducks raised with water troughs showed significantly lower foot pad scores at 9 d of age, but then significantly higher scores at 33 d of age compared to pin-metered water lines. * = P < 0.05, ** = P < 0.01, *** = P < 0.001.
