Pecking at string by individually caged, adult laying hens: colour preference and their stability

Bunches of string are attractive picking stimuli for laying hens. White or yellow bunches are preferred to blue or orange ones. Despite the brevity of presentation, the birds showed no evidence of habituation upon repeated exposure.

Effects of restricting access to litter trays on their use by caged laying hens

Hens with access to litter in an otherwise barren environment spent around 18% of their time in litter-related activities, consistent with the view that it is important to provide hens with substrate in which to forage and dust-bathe.

The effect of foraging material and perch height on feather pecking and feather damage in laying hens

Feather pecking was less frequent in pens with than without polystyrene block [foraging material]. On the other hand, feather damage in week 30 was significantly more pronounced in pens with low than with high perches, but not significantly influenced by...

Environmental enrichment for farm animals

Comprehensive review of the literature. It is desirable to socialize the animals to humans. Socialized animals are less fearful, grow more quickly, have higher rates of milk production, and show improved immune competence. Even brief contact with humans can decrease...

Perching behaviour and preferences for different perch designs among laying hens

Hens kept in pens were tested. No significant difference emerged when comparing time spent perching on single versus double wooden perches, soft versus hard perches, or round versus rectangular perches. .. Perching durations on wooden versus plastic versus metal perches,...

Preferences of growing fowls for different light intensities in relation to age, strain and behaviour

In the present study, it was found that older poultry preferred to be in dim light (6 lux) when inactive but in bright light when they were active. Some variation in ambient light intensity to provide both dimly and brightly...

Effects of prior video stimulation on open-field behaviour in domestic chicks tested with or without a familiar video image

Chickens who receive limited sensory stimulation are more likely to show fearfulness. Regular video stimulation was found to reduce chick's fear of an unfamiliar environment.

Responses of domestic chicks to selected pecking devices presented for varying durations

Our studies suggest that string [a pecking device] may be an attractive and practicable stimulus that affords chicken the opportunity to exercise a behaviour fundamental to their nature.
