Assessing preferences for adult vs juvenile features in young animals: newly-hatched chicks spontaneously approach red and large stimuli

This study shows that newly hatched chicks prefer red and large stimuli, suggesting they use these features to distinguish adults from juveniles without prior experience.

Newborn chicks show a preference for upward-moving stimuli over downward ones, suggesting an innate attraction to movement against gravity as a cue of animacy.
