Happy Chickens Lay Tastier Eggs: Motivations for Buying Free-range Eggs in Australia
Contributor(s):: Bray, Heather J., Ankeny, Rachel A.
Recent public interest in so-called “ethical” food production, and in particular the welfare of intensively housed farm animals, has been linked to an increase in sales of free-range eggs in several countries including Australia. Animal activist groups around the world have campaigned for the...
Use of outdoor ranges by laying hens in different sized flocks
Contributor(s):: Gebhardt-Henrich, Sabine G., Toscano, Michael J., Fröhlich, Ernst K. F.
In studies assessing outdoor range use of laying hens, the number of hens seen on outdoor ranges is inversely correlated to flock size. The aim of this study was to assess individual ranging behavior on a covered (veranda) and an uncovered outdoor run (free-range) in laying hen flocks varying in...
The impact of exhibit type on behaviour of caged and free-ranging tamarins
Contributor(s):: Bryan, Kayley, Bremner-Harrison, Samantha, Price, Eluned, Wormell, Dominic
The lack of appropriate stimuli associated with captive environments has been documented to cause several behavioural and physiological issues in captive species, including loss of natural behaviours, psychopathologies and decreased reproductive success. Providing free-ranging, naturalistic...
Fear and coping styles of outdoor-preferring, moderate-outdoor and indoor-preferring free-range laying hens
Contributor(s):: Campbell, Dana L. M., Hinch, Geoff N., Downing, Jeff A., Lee, Caroline
Free-range systems are increasing in popularity as outdoor access is perceived to improve hen welfare, but radio-frequency identification tracking of individuals shows not all hens access the range daily with some hens never going outside. The individual variation in range use may be correlated...
Managing Livestock Using Animal Behavior: Mixed Species Stocking and Flerds
Contributor(s):: Ed L. Frederickson
Mixed-species stocking can foster sound landscape management while offering economic and ecological advantages compared with mono-species stocking. Producers contemplating a mixed-species enterprise should reflect on several considerations before implementing this animal management strategy....
Low incidence of aggression in large flocks of laying hens
Contributor(s):: Hughes, B. O., Carmichael, N. L., Walker, A. W., Grigor, P. N.
The incidence of agonistic interactions was determined in a free range system with 700 birds and in a perchery system with 10 flocks of 300 birds. In both systems aggressive behaviour and agonistic interactions were infrequent. In the perchery, when the doors between adjacent pens of 300 laying...
Production and behaviour of laying domestic fowls in outside pens [abstract]
Contributor(s):: Hughes, B. O., Dun, P.
Two groups of 38 hens, commercial medium and light hybrid strains, were housed in outside pens, 23 x 21 m, and compared over a 20-month laying period with controls in groups of 4 in battery cages. They received the same laying mash in a feeding trough kept inside their hut, and almost all eggs...

Time budget-, behavioral synchrony- and body score development of a newly released Przewalski's horse group Equus ferus przewalskii , in the Great Gobi B strictly protected area in SW Mongolia
Contributor(s):: Souris, A. C., Kaczensky, P., Julliard, R., Walzer, C.
The Przewalski's horse (Equus ferus przewalskii) became extinct in the wild in the 1960s, but survived as a species due to captive breeding. There have been several initiatives to re-introduce the species in central Asia, but until now only two projects in Mongolia establish free-ranging...
Nest site choice and nest building of free-ranging domestic pigs due to farrow
Contributor(s):: Jensen, P.
Two groups of Swedish Landrace pigs were each kept in one of two adjacent semi-natural enclosures measuring 7 and 13 ha, respectively. During winter, the pigs had access to an uninsulated shelter of 12 msuperscript 2 with straw. For a total of 60 farrowings from 20 different sows, the nest site...

The effects of short term enrichment on learning in chickens from a laying strain ( Gallus gallus domesticus )
Contributor(s):: Krause, E. T., Naguib, M., Trillmich, F., Schrader, L.
Rearing and housing systems can have substantial effects on behaviour and physiology in domestic animals. In laying hens, several housing systems with different degrees of enrichment are in commercial use. Here, we tested effects of short term enrichment of housing conditions on the exploration...
Comparison of the behaviour of broiler chickens in indoor and free-range environments
Contributor(s):: Weeks, C. A., Nicol, C. J., Sherwin, C. M., Kestin, S. C.
The behaviour of broilers reared at pasture from 4 to 12 weeks of age on a low density diet supplied either indoors or outdoors, was compared with that of birds reared inside on deep litter. This single study found few differences in behaviour. Activity levels of birds outside were initially...
