One will discover that an infection on one chicken quickly spread through the rest of the brood. As is common, chickens are highly gregarious animals. Unlike man whose level of interaction can be limited depending on the character of the individual or the idiosyncratic nature of the context, chicken tend to move in groups. This confinement of one chicken to a brood of other chickens makes the chickens within the brood vulnerable to the infections current in a particular brood. Since this often happens, one way of limiting it is by fighting conditions which engender the cropping up of diseases at any particular time.
In environmentally controlled housing systems, birds are exposed to artificial light. So source, intensity, spectra and regimen of light had major impact in modern broiler management (Rozenboim et al., 1999). Long dark periods enhanced the growth more than continuous light but extended darkness without light provision resulted in impaired growth (Deaton et al., 1970). Gorden (1994) concluded that maximum benefit could be obtained by rearing broilers under lighting regimen of 1... ... middle of paper ... ...ncentrations and age at first egg in layer strains of domestic pullets.

The diet of a chicken consists of grains, lizards, small mice, and other plants and small animals (“Domestic Chicken”). While legend says chickens came from Greece, these flesh-faced creatures are now domesticated all over the world (“Domestic Chicken”). They can be found on farms, in poultry-production facilities, and even in fields either domesticated or wild (“Domestic Chicken”). Imprinting was first studied and experimented with in the 19th century by a man named Conrad Lorenz (“Animal Learning”). He learned that ducklings and goslings follow the movement and ... ... middle of paper ... ...of the results of Hutto’s work with goose eggs, one can understand that the sounds surrounding an egg can affect who the hatchling believes is mama.
Olfaction use in avian species Odors are broadly used for individual, sexual and species recognition in vertebrates and may be reliable signals of quality and compatibility when selecting mates. Yet, chemical signals in birds have rarely been investigated. In fact, birds exhibit a wide array of communication mechanisms, such as colors and songs, but rarely display obvious olfactory-driven behaviors. This discrepancy seen in the amount of information regarding olfactory use is due to the belief that birds do not have a well developed olfactory system compared to other animals. Because they do not have a well developed olfactory system, other perceptual cues, such as sight and audition, are seen as better predictors of behavior.

Thus, discussion on Federal Pigeons on foraging and vigilance behaviour will be based on references from Table 2 and Table 3. In Table 1, the observed behaviours of Dusky Moorhen, Ibis and Pacific Black Duck are grouped into five categories, namely resting, foraging, vigilance, mating and interactions respectively. Based on Table 4, similar behaviours in descending order of the amount of activity per unit time spent by Dusky Moorhen on land is as follow, Feeding (33.1%), Preen (26.9%), Rest (19.6%), Hunt Food (17.6%), Swim (2.2%), vocalizing (0.7%) and fighting (0%). With reference from Table 5,similar behaviours in descending order of the amount of activity per unit time spent by Dusky Moorhen in water is as follow, Feeding (35.2%), Swim (32.6%), Preen (15.2%), Rest (9.1%), Hunt Food (7.6%), Vocalizing (0.2%) and Fighting (0.13%). The listed behaviours for this activity are essential for animal survival (fitness) and reproduction in the ecology (Deag 1996).
