  1. T x G; Treatment by group interaction. G x E; Group by egg size interaction. T x E; Treatment by egg size interaction. AIC; Akaike information criterion. ∆ AIC; difference in AIC value. Nested models which differed by less than 2 AIC were interpretted as equally good, with the simplest best fitting model chosen. The final fixed effect structure is shown in bold
