Parameter estimates (± SE) and confidence intervals (CI; 95% and 85%) from the best supported mixed effect model explaining egg mass loss with experimental group (control/enlarged; n = 18/18 clutches) and days since the onset of incubation (“age”), and the interaction between experimental group and days from the onset of incubation.
