Use of space by domestic chicks housed in complex aviaries
To improve the understanding of the development of locomotor capacity in layer hens, we measured how female laying hen chicks (n = 120) of four different strains (LSL-lite, Hyline Brown, Dekalb White, Lohmann Brown; 3 groups of 10 chicks per line) utilized the ground, the air, elevated horizontal (platforms and perches) and inclined surfaces (ramps […]
Location tracking of individual laying hens housed in aviaries with different litter substrates
The laying hen industry is phasing out conventional cages in favor of other housing systems such as the aviary – designed to improve hen welfare by providing additional space and resources including a litter area. However, we do not know whether individual hens significantly vary in the time they spend in different areas of these […]
Development of physical activity levels in laying hens in three-dimensional aviaries
Levels of physical activity are known to be associated with a number of health and welfare parameters in laying hens, such as stronger bones. Despite this, we presently lack insight into the development of physical activity throughout the life of the laying hen. To close this knowledge gap, we measured physical activity levels of four […]
The effect providing space in excess of standards on the behaviour of budgerigars in aviaries
Budgerigars housed in conventional cages have no opportunity for some normal behaviours, in particular flight, and develop stereotyped behaviours. Increasingly aviaries are used for groups of budgerigars but the minimum space requirement to support normal behaviour is not known. We compared the behaviour of budgerigars in three aviaries, with 0, 28 and 56% increases in […]
