Table 1.

Percentage of time that white- and brown-feathered hens (n = 120) spent at the elevated feeder and elevated nest-box (calculated from the total number of minutes at the ground + elevated feeder, or nest-box) on week 0 week (baseline week before treatments were applied), and two, four and six weeks after treatment application. Within each treatment group, identical letters (a or b) represent least squared means that are statistically similar to one another.
