Incubation Temperature Affects Duckling Body Size and Food Consumption Despite No Effect on Associated Feeding Behaviors.

Incubation temperature had a significant (or marginally significant, after the Bonferroni correction) effect on apparent food consumption in all three trials (novel environment: P = 0.013, Fig 2A , Supplementary Table S6 ; familiar environment: P < 0.0001, Fig 2B , Supplementary Table S7 ; novel object: P < 0.0001, Fig. 2C , Supplementary Table S8 ) where, in all cases, given the same feeding behavior, high temperature-incubated ducklings consumed more food during a trial than low temperature-incubated ducklings.
