An investigation into the importance of foraging behaviour to laying hens
Bibliographic record
Abstract
The objectives of the research were (1) to determine which of three different characteristics (contrast, texture and manipulation) of a foraging substrate hens find most attractive, (2) to better understand the causal factors for foraging, (3) to investigate the extent to which locomotion is an essential component of foraging. Using substrates of small quartz pebbles it was shown in Experiment 1 that hens preferred manipulable to fixed substrates. In Experiment 2 it was shown that depriving hens of the opportunity to forage increased the amount of foraging behaviour in a decagon runway whereas increasing hunger did not. In Experiment 3 it was shown that locomotion during foraging was easily discouraged by making hens "work" in order to move to a new section of the decagon runway; other elements of foraging also declined in this treatment. The results suggest that foraging is an important behaviour pattern that has causal factors different from those governing hunger.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
