The objective of this trial was to evaluate spatial distribution, nest and perch usage, and preference of Lohmann Brown (BH) and Bovan White (WH) Leghorn hens raised in an aviary system. At 5 wk, 400 floor raised pullets, BH and WH strains, in equal numbers, were placed into 8 modified Big Dutchman Natura aviary units. Each aviary unit had 3 tiers with perches and an indoor litter area. At 25 wk, the number of birds was recorded by scan sampling every 4 h. The number of birds perching in each aviary unit was recorded every 4 h at 15, 25, …
