Name: The Effect of Puberty on Fear Behaviour in Laying Pullets
Description: Puberty is a critical period characterized by a multitude of physiological and behavioural changes. In humans and rats, the changes in fear behaviour are well documented. In poultry, however, this topic remains largely under-researched. At 4 different developmental ages (pre-puberty, early puberty, late puberty, and post-puberty), brown-feathered layers will undergo a combined emergence/novel arena/novel object fear test to assess changes in fearfulness and threat processing throughout puberty.

Not agitated behaviours includes exploring, sitting, preening, ground pecking, wall pecking, novel object pecking, relaxed standing, and dustbathing. |
| percent_ag | Percentage of time during the test spent agitated | The percentage of time spent agitated. This is calculated as "total_ag_sec" divided by "total_time_arena_sec", then multiplied by 100. |
