Changes in olfactory responsiveness by the domestic chick after early exposure to odorants
Article Abstract:
Evidence suggests that odorants are important for forming attachments by domestic chicks but there is little evidence that nestlings remember odorants presented soon after they are hatched. A new study investigates whether early exposure to nonaversive odorants alters a chick's responses to natural odours, such as food, feathers and faeces of adult chicken. The study concludes that chicks learn about their olfactory environment during the latter part of incubation and in the early posthatching period.

Observational learning in day-old chicks using a one-trial passive avoidance learning paradigm
Article Abstract:
Experiments conducted on day-old chicks showed that they can learn to avoid an aversive stimulus by observing responses from other chicks. However, results showed unclear evidences in the use of sensory cues or types of behavior by chicks to maintain avoidance. The experiments involved allowing a chick to peck at a bead coated with the bitter-tasting methylanthranilate, while another chick was allowed to observe the behavior of the actor chick.

Prenatal light exposure affects early feather-pecking behavior in the domestic chick
Article Abstract:
The early feather pecking that is a form of social exploration and the lateralization of functions that can be influenced by light exposure late in embryonic development is proposed. The effects of prenatal light exposure on early posthatching feather-pecking behavior in domestic chicks is investigated.
