“…Social behavior provides the framework for predictable relationships among members of a group through social dominance (Estevez et al, 2007). Social discriminations are made by hens under the stress of competition (Syme et al, 1983), and animals with higher ranks would have priority of access to resources (Banks et al, 1979). In this study, ample amount of feed, feeder space and compartment space were available to the hens to avoid potential competition due to feed or space limitations.…”

Light intensity, spectrum and pattern may affect laying hen behaviors and production performance. However, requirements of these lighting parameters from the hens' standpoint are not fully understood. This study was conducted to investigate hens' needs for light intensity and circadian rhythm using a light tunnel with five identical compartments each at a different fluorescent light intensity of <1, 5, 15, 30 or 100 lux. The hens were able to move freely among the respective compartments. A group of four W-36 laying hens (23 to 30 weeks of age) were tested each time, and six groups or replicates were conducted. Behaviors of the hens were continuously recorded, yielding data on daily time spent, daily feed intake, daily feeding time, and eggs laid under each light intensity and daily inter-compartment movement. The results show that the hens generally spent more time in lower light intensities. Specifically, the hens spent 6.4 h (45.4%) at 5 lux, 3.0 h (22.1%) at 15 lux, 3.1 h (22.2%) at 30 lux and 1.5 h (10.3%) at 100 lux under light condition; and an accumulation of 10.0 h in darkness (<1 lux) per day. The 10-h dark period was distributed intermittently throughout the day, averaging 25.0 ± 0.4 min per hour. This hourly light-dark rhythm differs from the typical commercial practice of providing continuous dark period for certain part of the day (e.g. 8 h at night). Distributions of daily feed intake (87.3 g/hen) among the different light conditions mirrored the trend of time spent in the respective light intensity, that is, highest at 5 lux (28.4 g/hen, 32.5% daily total) and lowest at 100 lux (5.8 g/hen, 6.7%). Hen-day egg production rate was 96.0%. Most of the eggs were laid in <1 lux (61.9% of total) which was significantly higher than under other light intensities ( P < 0.05). Findings from this study offer insights into preference of fluorescent light intensity by the laying hens. Further studies to assess or verify welfare and performance responses of the hens to the preferred lighting conditions and rhythm over extended periods are recommended.

“…Various studies indicate that aggressive dominance is significantly increased in residents of flocks of fowl against familiar or unfamiliar newcomers (Schjelderup-Ebbe, 1922;Allee et al, 1939;Guhl and Ortman, 1953;Guhl, 1961;Banks et al, 1979;Rajecki et al, 1981). Surprisingly, the only experimental study reporting some advantage of a 22 h prior residency in this species is that of Zayan et al (1983).…”

We examined the effect of prior victory or defeat in the same site as that of a subsequent encounter on the outcome of dyadic encounter of domestic hens by placing them in two situations: In the first set of dyads, two unacquainted hens having experienced prior victory were introduced in the site where one had experienced victory. In the second set, two unacquainted hens having experienced defeat were introduced in the site where one had recently lost. Results indicate that victories are equally shared between individuals with prior victory experiences, while familiarity with the meeting site did not give any advantage. However, hens having previously lost were disadvantaged when the encounter occurred in the same site as that of their prior defeat. This demonstrates that previous social experience in a site is more important on the outcome of subsequent encounters for losers than winners. Losers seem to associate the site with the stressful effect of losing or being more easily dominated.

“…whether higher ranking hens have preferential access to the most attractive nesting locations (Freire et al, 1998;Rietveld-Piepers et al, 1985). Social status affects priority access to other resources such as feed (Banks et al, 1979;Collias and Collias, 1967) and space (Keeling and Duncan, 1989;Odén et al, 2004) and we hypothesized that if there was a preferred nest, social status would affect nest choice.…”
