Replication Data for: Rearing Laying Hens: environmental complexity and genetic strain affect pullet but not chick performance in a T-maze learning task

We used two learning tests to test three hypotheses using chicks and pullets of brown and white layer strains reared in cages and aviaries of varying complexity. 1) Does increased spatial complexity during early life improve the performance of laying hen chicks/pullets in a T-maze? 2) Does chick/pullet performance in a two-dimensional learning task differ between genetic strains? 3) Is there an interactive effect of genetic strain and rearing environment on performance in the tasks?
