Key Points

To examine how threat processing and fear behavior develop in laying hen pullets during puberty.
Experimental treatments assessed standard vs one-week-delayed puberty.
Latency to enter the neutral arena (NA) and approach the novel object (NO) was measured over different testing ages.
Agitation was recorded post-photostimulation.
Latency to enter the NA and approach the NO increased with age.
Agitation was highest after all birds were photostimulated at the third time point (TP3).
Pullets before puberty (TP1) reacted most fearfully to the NO appearance.

Abstract

• Experimental treatments resulted in standard vs one-week-delayed puberty. • The latencies to enter the NA and approach the NO increased with testing age. • Agitation in the NA was highest after all birds were photostimulated (TP3). • Pullets pre-puberty (TP1) were most likely to react fearfully to the NO appearance. • Pubertal pullets’ fear behaviour development differed from well-studied mammals.
