The file contains data on the mass (g) of mice used for rearing experimental broods, egg-laying date and weighting date, female treatment (C=Control, W=Weighted), body mass (g) of females before/after handling and (for weighted females only) weighting, at day 1 after egg-hatching and at larval dispersal (before and after handling and washing dirt around the lead weight), brood mass (g) at different larval stages, mass (g) of the lead weights, offspring survival rate until dispersal and eclosion, date and time each 30-min observation has been performed, frequency (number of scans out of 30 scans) each behaviour has been recorded, and the total number of larvae begging.
