Ranging Behaviour of Commercial Free-Range Laying Hens.
In this study, the range use and behaviour of laying hens in commercial free-range flocks was explored. Six flocks were each visited on four separate days and data collected from their outdoor area (divided into zones based on distance from shed and available resources). These were: apron (0-10 m from shed normally without cover or other enrichments); enriched belt (10-50 m from shed where reso...
متن کاملIndividual Ranging Behaviour Patterns in Commercial Free-Range Layers as Observed through RFID Tracking
In this exploratory study, we tracked free-range laying hens on two commercial flocks with Radio Frequency Identification (RFID) technology with the aim to examine individual hen variation in range use. Three distinct outdoor zones were identified at increasing distances from the shed; the veranda [0-2.4 m], close range [2.4-11.4 m], and far range [>11.4 m]. Hens' movements between these areas ...
متن کاملRanging Behaviour of Commercial Free-Range Broiler Chickens 2: Individual Variation
Little is known about broiler chicken ranging behaviour. Previous studies have monitored ranging behaviour at flock level but whether individual ranging behaviour varies within a flock is unknown. Using Radio Frequency Identification technology, we tracked 1200 individual ROSS 308 broiler chickens across four mixed sex flocks in two seasons on one commercial farm. Ranging behaviour was tracked ...
متن کاملS83 Egg Shell Colour in Free Range Laying Hens
Loss of shell colour in brown-egg layers is a shell quality issue in Australia and is periodically associated with free range egg production. This study investigated the loss of shell colour that occurs in some flocks of free range laying hens. Hens laying pale-coloured egg shells on a commercial free range farm were transferred to cages in an experimental facility. Egg quality was measured imm...
